摘要

本文报道了一种亚纳秒光学参量放大器(OPA)系统在硼酸钡(BBO)晶体中的实验实现，该晶体由被动调q Nd:YAG微激光系统的三次谐波泵浦，并由光子晶体光纤(PCF)中产生的连续介质播撒。在470 ~ 660 nm的可见光谱范围和768 ~ 1450 nm的空闲波长范围内产生宽带连续信号波长可调性。在实验数据的基础上，给出了BBO光参量放大器的数值模拟结果。亚纳秒BBO OPA的最大输出功率受到泵浦辐射和种子辐射光谱功率密度对BBO晶体激光损伤的限制。我们还注意并讨论了种子辐射对BBO OPA输出辐射特性的影响。数值模拟结果与实验数据基本吻合。

Investigation of a widely-tunable subnanosecond BBO-based optical parametric amplifier

We report an experimental realization of a subnanosecond optical parametric amplifier (OPA) system in a beta barium borate (BBO) crystal pumped by the third harmonic of a passively Q-switched Nd:YAG microlaser system and seeded by the continuum generated in a photonic crystal fibre (PCF). It yields broadband continuous signal wavelength tunability in the visible spectrum range from 470 to 660 nm and the idler wavelength from 768 to 1450 nm. Besides the experimental data, the numerical simulation results of the BBO optical parametric amplifier are presented. The maximum output power of the subnanosecond BBO OPA is limited by laser induced damage in the BBO crystal by the pump radiation and seed radiation spectral power density. We also notice and discuss the effect of seed radiation on BBO OPA output radiation characteristics. The numerical simulations qualitatively agree with the experimental data.
