Abstract

Abstract

In order to meet the requirement of high-energy laser output from a vacuum resonator to atmosphere and reduce the effect of windows thermal deformation on laser beam performance, the paper introduces a technical solution which can reduce laser irradiation on solid window. In the solution, solid window is driven by high torque hollow DC motor and rotates uniformly. The isolation between vacuum resonator and environmental atmosphere is fulfilled by high-precision dynamic seals. And thus the irradiation on window is more uniform, i.e. the window temperature and stress gradient are decreased greatly, the laser beam quality is improved, and cracks in window can be avoided in long-time running. The results show that the solution is of several advantages, such as small volume, light weight, compa
- rotating window,
- high-energy laser,
- beam quality,
- long-time running,
- thermal deformation
