Abstract

This paper deals with the third harmonic conversion technology on the high power glass laser for fusion application, The details of the fabrication and alignment procedures of a 36cm dia-meter segmented KDP crystal cell with an index matching fluid, and the energy monitor system for third harmonic light without distortion on the beam patterns are described. The conver-sion efficiency from 1.05μm to 0.35μm was found to be 60±10% for 12 beams.
