CO2 laser cutting machine is a gas laser using CO2 gas as working substance. The discharge tube is filled with CO2, helium, nitrogen, hydrogen and xenon, mainly CO2 and others. High voltage on the electrode and discharge in the discharge tube have laser output on the germanium mirror.
There are abundant spectral lines, and there are dozens of spectral lines near the 10 micron laser output. The output beam has high optical quality, good coherence, narrow line width and stable operation. With relatively large power and relatively high energy conversion efficiency, the energy conversion efficiency can reach 30 to 40%, which is also higher than that of general gas lasers.
The working principle of CO2 laser cutting machine:
Principle of laser generation: The discharge tube of CO2 laser is filled with a mixed gas of CO2, N2, He, etc., and the ratio and total pressure can be varied within a certain range. CO2 lasers use the vibration between the CO2 molecules and the transition between the energy levels to generate laser light.
The applicable object of CO2 laser cutting machine:
CO2 laser cutting machine is mainly used for cutting non-metallic materials, such as cloth, the jeans we wear, some holes or old colors are processed through this CO2 laser cutting machine. There are also leather, plastic, acrylic and other can also use CO2 laser cutting machine. If the power is high, CO2 laser cutting machine can also cut metal. But the accuracy is generally not too high, and can not cut too thick. Compared with optical fiber laser cutting machine is still relatively inadequate, so the use of metal cutting is less.
Definition of UV laser:
Ultraviolet laser cutting machine is a cutting system using ultraviolet laser. It utilizes the characteristics of ultraviolet light and has higher precision and better cutting effect than traditional long wavelength cutting machine. The use of high-energy laser sources and precise control of the laser beam can increase processing speeds and achieve more accurate machining results.
Advantages of UV lasers:
High-performance UV lasers have short wavelengths, high beam quality, and high peak power. Reduce the size of the focused spot to ensure the processing accuracy, different thickness, different materials, different graphics can be cut.
The working principle of UV laser:
Except for free electron lasers, the basic working principles of various lasers are the same. The indispensable condition for generating laser light is that the ion number is reversed or the gain is greater than the loss, so the indispensable components of the device are the excitation (or pumping) source and the working medium with the metastable energy level. Excitation is the excitation of the working medium to excite the excited state, creating conditions for achieving and maintaining the population inversion. The incentive methods include optical excitation, electrical excitation, chemical excitation and nuclear energy excitation.
The applicable object of UV laser cutting machine:
UV laser is especially suitable for cutting and marking of hard plate, soft and hard joint board, soft plate and its accessories.
