Abstract

We demonstrate the generation of compressed, transform-limited 250-fs pulses, tunable in the near infrared, by means of synchronously pumped optical parametric oscillation in periodically poled lithium niobate. The almost 20-fold compression from the 4-ps pulse duration of the cw mode-locked Nd:YLF pump results in signal peak powers well in excess of the pump power.

摘要

我们展示了通过在周期极化铌酸锂中进行同步泵浦光学参量振荡，产生压缩的、变换极限的250飞秒脉冲，该脉冲在近红外波段可调谐。连续锁模Nd:YLF泵浦源的4皮秒脉冲持续时间被压缩了近20倍，从而使信号峰值功率远超过泵浦功率。
