Mitigating Damage of the Ghost in High Power Laser Facilities by Real-Ray Trace
Ghost reflections are a major consideration in the optical design of the high-power laser facilities. A thorough ghost analysis has been carried out for the technical integration line (TIL), which is the full scale prototype for Shenguang-Ⅲ laser facility (SG-Ⅲ), with a method of combination of paraxial ray tracing and real ray tracing. This paper takes one of the “dangerous surfaces” as example, which is the front plane of a window in Pockels cell, simulating the energy distribution graph on it by numerous real-ray tracings. According to the shape of ghost energy graph and its corresponding optical structure, suggestions are made to effectively mitigate the damage on the studied optical surfaces.
