Abstract
Stable subpicosecond infrared pulses in the spectral region of 4.5-11.5 microm are generated by difference-frequency mixing in AgGaS(2). The system uses femtosecond pulses from a Ti:sapphire regenerative amplifier and from a tunable traveling-wave dye laser. The infrared pulses have a duration of 400 fs, an energy of more than 10 nJ, and a repetition rate of 1 kHz.
摘要
通过在AgGaS₂中进行差频混频，在4.5 - 11.5微米的光谱区域产生了稳定的亚皮秒红外脉冲。该系统使用来自钛宝石再生放大器和可调谐行波染料激光器的飞秒脉冲。红外脉冲的持续时间为400飞秒，能量超过10纳焦，重复频率为1千赫。
