Abstract

We present a non-collinear optical parametric amplifier (NOPA) delivering sub-10-fs pulses with 420 nJ of pulse energy. The system is driven by microjoule pulses from an Yb:KYW oscillator with cavity-dumping and a subsequent single-stage rod-type fiber amplifier at 1-MHz repetition rate. The ultrabroadband seed is based on stable white-light generation from 420 fs long pulses in a YAG plate.

摘要

我们展示了一种非共线光学参量放大器（NOPA），它能产生脉冲能量为420 nJ、脉宽低于10 fs的脉冲。该系统由一个采用腔倒空技术的Yb:KYW振荡器产生的微焦耳脉冲驱动，随后是一个重复频率为1 MHz的单级棒状光纤放大器。超宽带种子源基于YAG晶体板中420 fs长脉冲产生的稳定白光。
