在精确计算包括空气在内的钛蓝宝石激光器腔内色散的基础上,通过合理选取啁啾反射镜,直接用简单的四镜腔结构获得了光谱覆盖540-1030nm波段的超连续激光光谱.进一步探讨分析了实现超过一个倍频程光谱宽度的有关物理与技术。
Through calculation of intra-cavity dispersion of Ti : sapphire laser including air, we obtained super-continuum extending from 540 to 1030 nm using four-mirror cavity composed of proper chirped mirrors. The technique to generate an octave-spanning femtosecond pulse was further discussed.
