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。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 β=3～4 while the average laser power was 2kW.
