摘要

在无阶梯诱导空间非相干光束平滑技术中,用作前端的部分相干源是重要的组成部分.介绍了利用准分子激光进行的部分相干源实验,发现聚四氟乙烯是一种较理想的散射材料.研究了聚四氟乙烯散射源对光束的散射性能,给出了光束均匀性、空间相干性和能量转换效率等参数.

Abstract

Partial coherence source is a key part in the laser system using echelon-free introduced spatial incoherence beam smoothing technique. Different kinds of partial coherence sources have been studied experimentally for improving the uniformity of laser intensity distribution. It is found that the source produced by excimer laser scattering on the surface of a teflon plate is ideal. The properties of this kind of source are studied. As a result, the uniformity of source beam intensity distribution, the beam spatial coherence and energy transfer efficiency of the source are obtained.
