Abstract

White light continuum seeded noncollinear optical parametric amplifier driven by Yb:KGW master oscillator power amplifier (MOPA) system is reported. The demonstrated design provides amplification of broadband pulses at 800 nm up to 20 µJ energy at 1 kHz repetition rate and can be used as simple and reliable frontend source for systems producing high intensity few-cycle pulses. The amplified spectral bandwidth allows for <7 fs pulse durations and preliminary compression of partial spectrum yields sub-10 fs pulse.

摘要

报道了由掺镱钽酸钆主振荡器功率放大器（MOPA）系统驱动的白光连续谱种子非共线光学参量放大器。所展示的设计能够在1 kHz重复频率下将800 nm的宽带脉冲放大至20 μJ能量，并且可用作产生高强度少周期脉冲系统的简单可靠前端光源。放大后的光谱带宽可实现<7 fs的脉冲持续时间，对部分光谱进行初步压缩可产生亚10 fs脉冲。
