Simulation Of Resonator Of High Power Transverse Flow CO₂ Laser

The laser manufacturing has been rapidly developed with the development of the domain of laser application, which poses a challenge to the traditional design methods of laser. It is an important problem to be solved that the design methods of laser product must be geared to the constantly changing demands of market. As a key part, the resonator of laser exerts a direct influence on some important indexes such as the output power of laser, mass and so on. In the era of information and globalization, advanced manufacturing technology is important to the improvement of design for resonator, which can also shorten the period of design, Therefore, it can be concluded that the simulation of the High Power TF CO2 laser (HP TF laser) is meaningful for both theoretical research and practical application.Combined with the technology of virtual prototyping, this paper expounds it is necessary and feasible to research resonator in HP TF Laser through the technology of simulation. Considering that the distributive state of Gauss Beam of light can show the characteristic of output light's mass, a distributed simulated system for Gauss Beam of light, through which resonator in 2KW TF laser is simulated, is built with Simulink on the basis of analyzing its distributed characteristic. The description of temperature field in resonator in HP TF laser is gotten by using non-linear finite element method (FEM). Based on the experimental data of the temperature field in resonator of 2KW TF CO2 laser, processed by interpolating, distributed graph of temperature field, which proved the correctness of the result from simulation, is gained.
