千瓦级COIL-UR90实验研究
-
摘要: 首次报导了千瓦级化学氧碘激光器（COIL）采用束转动90°环形非稳腔(UR90)的实验结果,测量了输出光斑的近场相位分布及远场强度分布, 当激光输出平均功率为2kW时,光束质量因子b =3~4。

Abstract: This is the first experimental result on a 2kW chemical oxygen iodine laser (COIL) using an unstable ring resonator with 90°beam rotation(UR90°). The distribution of near-field phase and far-field intensity were measured. The measured value of beam quality was b =3~4 while the average laser power was 2kW. -
