Abstract

We present a novel generic approach for pulsed light generation in the visible spectrum. We demonstrate how the circulating field of a high finesse laser can be efficiently cavity dumped through sum-frequency mixing with externally injected high peak power single pass pulses. Periodically poled KTP is used as the nonlinear medium to minimize the peak power requirement of the injected beam. The experimental setup consists of a high finesse 1342 nm Nd:YVO4 laser cavity and a passively Qswitched Nd:YAG laser. Yellow pulses at 593 nm are generated.

摘要

我们提出了一种在可见光谱中产生脉冲光的新型通用方法。我们展示了如何通过与外部注入的高峰值功率单通脉冲进行和频混频，有效地将高精细度激光器的循环场从腔中取出。周期性极化的磷酸钛氧钾（KTP）被用作非线性介质，以最小化注入光束的峰值功率要求。实验装置由一个高精细度的1342纳米掺钕钒酸钇（Nd:YVO4）激光腔和一个被动调Q的掺钕钇铝石榴石（Nd:YAG）激光器组成。产生了593纳米的黄色脉冲。
