What is the future of CO2 laser?
CO2 laser technology with its unique wavelength, power and spectral purity, still survive in the market and continue to flourish. Because many natural materials and synthetic materials have a strong absorption peak at 9 ~ 12μm, which happens to be the wavelength of the output wavelength of the CO2 100mw laser pointer, which provides a great opportunity for CO2 lasers in the field of material processing and spectral analysis. This band is also included in the atmosphere transmission window, and therefore is ideal for many sensing and ranging applications.
A typical CO2 laser is formed by the generation of a gas discharge from a mixed gas containing a CO2 molecule. Because the molecular vibrations and rotations are very close to each other, the energy generated by the CO2 molecules transition between these levels is lower and longer than visible and near infrared. CO2 lasers can provide a power range from milliwatts to tens of thousands of watts, can be used to manufacture equipment, can also be used for strong cutting. Because CO2 50mw green laser have very high spectral purity, line width up to 1kHz or less without sacrificing power, conversion efficiency of up to 10%. These features enable CO2 lasers to be qualified for new applications in materials processing, laser ranging and radar, thermal vision assistance and targeted medical applications.
Despite these long-term advantages, CO2 lasers have been challenged in some ways. Fiber lasers and quantum cascade lasers have been extended to a number of applications previously dominated by CO2 lasers. In industrial applications, high-power fiber lasers can provide greater efficiency, the energy can be better absorption of metal materials, and more cost advantages. However, CO2 lasers are still the only way to process many nonmetallic materials because these materials do not absorb the near-infrared wavelengths of fiber lasers.
Quantum cascade 1mw laser pointer can produce wavelengths in the range of 2 to 12 μm and are more compact and have become an important tool in spectroscopy applications. However, many sensors in the 8 ~ 12μm long wave infrared band, spectral sensitive industrial and medical applications require higher power, better spectral purity, excellent coherence and stable spatial pattern, which only CO2 lasers can achieve.
Although CO2 lasers have ended as a "one-size-fits-all solution for all applications", with the advent of new materials and increasingly stringent industrial and scientific processing requirements, these require new dedicated lasers that require a real The value proposition has a deeper understanding of the technology and requires a completely different way to manufacture and promote CO2 lasers. CO2 lasers are addressing these new challenges. In the manufacturing, this new model needs to adjust the various indicators of CO2 red laser pointer, in close cooperation with the specific needs of customers. In the market, from the previous average power and "according to tile price" value proposition, into a customized solution, according to the specific needs of materials and applications, the design of the laser pulse shape, peak power, dedicated wavelength and stable Sex.
CO2 lasers are considered to be the best tools for generating extreme ultraviolet (EUV) radiation through laser-generated plasmas (LPP) when attempting to extend Moore's Law. This 13.5 nm EUV light is produced by vaporizing the molten tin droplets of tin. Other lasers, such as Nd: YAG, have also been tested for this application, and the results show that they are less efficient in producing optical thin plumes with higher speed and higher quality plasma properties because tin has a higher effect on CO2 5mw green laser irradiation Reflectivity. In order to produce EUV light, CO2 lasers need to provide a series of wavelengths of 10.6μm, optical quality near perfect, high speed and exactly the same pulse, with the semiconductor industry required cleanliness, accuracy and repeatability.
