摘　　要：测量了在脉冲宽度为750fs、波长为616nm强光作用下掺半导体玻璃RG645 Schott滤光片的饱和吸收特性,同时观察到在高功率密度下光束经玻璃后产生明显的自聚焦现象。Employing intense laser beams at 6l6nm and 750fs pulse width, we measured the saturable absorptive property of Schott filters RG645 made of semiconductor doped glass, and observed clearly self-focusing during the beam passed through the sample at high power densities.

关 键 词：饱和吸收 滤光片 激光 玻璃半导体
