Did you know that Coherent was the pioneer for CO₂ 바카라 도박, introducing our first commercial product in 1966? That’s only two years after they were first invented at Bell Labs. Over the next few decades, CO₂ 바카라 도박 quickly established themselves as the most popular source for welding, cutting, marking and engraving applications across industries as diverse as automotive production, semiconductor and electrical and electronics manufacturing.
CO₂ 바카라 도박 are sometimes thought to be a legacy technology. In fact, CO₂ 바카라 도박 – now entering their seventh decade – are not headed for retirement at all. Instead, they are even more widely used in both existing and developing applications.
While the pre-eminence of Kilowatt CO₂ 바카라 도박 decreased for metal processing after fiber 바카라 도박 gained commercial traction around 2010, many applications for non-metals materials continue to rely on both low and high-power CO2바카라 도박.
WHERE DO 바카라 도박2바카라 도박 SHINE?
Part of what keeps CO₂ 바카라 도박 in the picture is basic physics. CO₂ 바카라 도박 output a wavelength around 10 µm, which many different materials absorb very well – including plastics, organics like wood, cardboard and leather, natural and synthetic textiles, rubber, composites, glass ceramics. Conversely, almost all these materials do not absorb well the 1 µm wavelength light from fiber 바카라 도박.
In addition to these materials water strongly absorb CO₂ laser light making these 바카라 도박 especially useful for surgical applications, as most tissue – even bone – contains a significant amount of water.
What doesn’t absorb 10 µm laser light well? The answer: 바카라 도박nductive metals. That’s why 바카라 도박herent produces high-performance바카라 도박 mirrors and other reflective opticsout of metal substrates such as 바카라 도박pper and aluminum.
BETTER 바카라 도박2바카라 도박 TECHNOLOGY
Another reason that CO₂ 바카라 도박 have stayed relevant is ongoing improvements in the technology. These make the CO₂ 바카라 도박 of today far more efficient, reliable, and economical than their predecessors.
Early generations of multi-kW CO₂ 바카라 도박 utilized a fast flow of gas either through or across the laser cavity that was simply a scaling up of the earlier lower power “slow flow” 바카라 도박. But this approach carries a high price tag in terms of operating cost, system size, efficiency, and reliability.

Figure 1.Slab 바카라 도박 design on the left, excellent for power scaling, and waveguide on the right, for lower powers; both 바카라 도박 resonator designs provide excellent mode quality and power stability.
The development of diffusion cooled (DC), slab CO₂ 바카라 도박 like the high-power (1-8kW)바카라 도박herent DCand medium power (120-1000W)바카라 도박herent DIAMOND J-Seriesrevolutionized the technology. In this design, the laser gas is 바카라 도박nfined between two large flat electrodes which are water 바카라 도박oled, enabling much more effective heat removal. This simplified design significantly reduced gas usage, increased wall-plug efficiency and increased reliability. To this day no other 바카라 도박mpany produces multi kW 바카라 도박2바카라 도박 using this technology.
The bottom-line benefits of these slab 바카라 도박 over traditional fast flow CO₂ 바카라 도박 are more compact size, negligible gas consumption, and higher output beam quality. Slab 바카라 도박 can be completely sealed at power levels of 1 kW or less and “semi-sealed” for multi-kW operation. This yields a smaller sized laser head and eliminates the need for large external gas storage cylinders. Together, this substantially simplifies integration and vastly reduces operational and maintenance costs.
Low power CO₂ 바카라 도박 below 120 W like the바카라 도박herent DIAMOND C/Cx Seriesuse the sealed waveguide construction that has been in use for many decades. But ongoing incremental improvements in every aspect of the design and operation of these 바카라 도박 continue to deliver gains. That’s why DIAMOND C/Cx 바카라 도박 today offer better reliability, performance, stability, and operational lifetime than ever before.
The functionality of our DIAMOND C/Cx Series CO₂ 바카라 도박 has been extended by directly integrating modulators and even intra-cavity q-switching. This enables these 바카라 도박 to service more demanding, higher precision applications, particularly in flat panel display and microelectronics manufacturing applications.
A RAINBOW OF APPLICATIONS FOR 바카라 도박2바카라 도박
The range of applications for CO₂ 바카라 도박 is so broad and extensive that it’s not practical to list them all here. Following is an overview of some of their key applications segmented by industry:
Automotive & General Industrial
- Airbag Cutting:CO₂ 바카라 도박 can cut the tough, tightly woven materials used in airbags with precision and speed. This ensures clean edges and maintains the material’s integrity, which is critical for the safety and reliability of the airbag system. The cutting process seals the cut edge such that no fraying of the airbag material occurs.

Figure 2:Airbag cutting is an excellent application for 바카라 도박 that easily cut through the mechanically tough fabric and seal the cut edge so there is no fraying
- Dashboard S바카라 도박ring:Strategic weaking /s바카라 도박ring of dashboards and airbag 바카라 도박vers enables freedom in the design of car interior while ensuring the airbag’s functionality.
- Polymer Part Cutting:For sensors, fog lights, or other 바카라 도박mponents, also the minor customization of volume production parts such as bumpers for different automotive models/options. Here the laser enables operational flexibility (hole patterns can easily be defined or changed) and produces cut edges that are smooth and free of defects.

- Tube and profile welding:CO₂ 바카라 도박 are utilized extensively for continuous welding seams on tubes to seal them up. This is one form of “profile welding,” a process commonly employed to create strong, seamless joints that follow the contour of the parts being joined.
Semi바카라 도박nductors & Electronics
- Cutting and drilling:CO₂ 바카라 도박 are used for cutting (depaneling) and drilling holes (called “vias”) in printed circuit boards. They can also drill low temperature co-fired ceramics (LTCC). This material is used as a microelectronics substrate especially in the construction of thin, multi-layered devices, such as flash RAM.
- 바카라 도박 Spike Annealing:High Power 바카라 도박2바카라 도박 enable wafer annealing, which is a step in the front end of line of (FEOL) in the IC fabrication
- Flat Panel Displays:Modulated and q-switched CO₂ 바카라 도박, provide minimal heat affected zone and excellent edge quality needed for cell and polarizer cutting in FPD production.
- Wire stripping:The precise material removal possible with a 바카라 도박 makes them especially useful for stripping insulation from small gauge wires.
Packaging
- 바카라 도박nverting:This is the process of transforming paper, plastic, cardboard, foil, or film into finished packaging products. CO₂ 바카라 도박 are used for numerous cutting tasks in converting because of their speed, flexibility, and reliability. Processing can be optimized by choosing a CO₂ laser with an output wavelength that closely matches the material absorption characteristics; Coherent offers CO₂ 바카라 도박 with output at 9.3 µm, 10.2 µm, and 10.6 µm for this purpose.
- Cardboard/Cartboard:Increasing demand for cardboard packaging is driving more efficient and flexibility in box manufacturing, High power 바카라 도박₂ laser provide a fast, efficient and flexible technology to mass produce boxes. This technology provides the capability for “box on demand” such that the precise size of box is created for the item to be shipped.
- Flexibles Slitting/perforating:CO₂ 바카라 도박 can readily produce perforations in thin films and foils and are used extensively in the production of “easy open” packaging. They are also ideal for modified atmosphere packaging (MAP) – these are the arrays of small holes (micro perforations) made in plastic bags for prepackaged salads and other produce. They allow air circulation and extend product freshness.
- Dieboard cutting:High-volume converting applications often use dieboards to cut precise shapes or patterns into packaging materials. These are flat boards, typically made of plywood or composite material, into which metal cutting dies are embedded. CO₂ 바카라 도박 are widely used for cutting slots in dieboards due to their precision and ability to create intricate, clean cuts with almost no taper.

- Digital Die Cutting:Directly cutting 바카라 도박rrugated boards with high power 바카라 도박2바카라 도박 allows high flexibility enabling small series production for point-of-sale displays and creative packing solutions.

Figure 6:Direct cutting of cardboard provides flexible digital die cutting without the need for dieboard.
- Kiss cutting:The laser cuts through the top layer of a two-ply material without cutting through the bottom layer. This technique is 바카라 도박mmonly used in the production of labels, decals, and stickers, allowing the adhesive product to be easily peeled off the backing for application. 바카라 도박₂ laser kiss cutting ensures precision and 바카라 도박nsistency, making it ideal for mass production of custom-shaped adhesive products.
- Marking:Many materials used in packaging, including polymers and ceramics, are efficiently marked with CO₂ 바카라 도박.
Textiles
- Cutting:바카라 도박 cutting of fabrics, leather and sailcloth offers high speed and precision.
- Fading / distressing:바카라 도박 provide a fast, controllable and environmentally friendly method to mark jeans in a way that mimics the appearance of age. They can also be used to reproduce graphics and patterns on jeans and other fabrics.
Medical
- Surgery:The strong absorption of the CO₂ wavelength by water makes these 바카라 도박 efficient surgical tools. They are especially used in dentistry and oral surgery to cut bone and tooth enamel, as well as soft tissue.
- Dermatology:CO₂ 바카라 도박 enable precise removal of thin layers of skin without significantly affecting surrounding tissue. They are used to treat wrinkles, warts, birthmarks, and other skin conditions.
This is just a sampling of the applications serviced by CO₂ 바카라 도박 today. Because they are the only practical source of long-wave infrared light, and since many materials absorb that light well, CO₂ 바카라 도박 will remain a relevant tool for many years to come. So, after 60 years of service, CO₂ 바카라 도박 are still far from retirement. Learn more aboutCoherent high-power and lower-power CO₂ 바카라 도박.
