摘要

介绍了基于“突发”模式Nd:YAG激光器改进的MHz帧流诊断技术的最新进展。特别是，PDV系统可以测量平面上速度高达1 MHz的速度，以及定制的光学参量振荡器的初步结果，该振荡器专门设计用于突发模式泵浦。描述了宽波长可调脉冲序列的生产，单个脉冲能量为阶mJ，谱线宽度为阶1cm /sup -1/。

Recent enhancements to the OSU burst mode laser and MHz rate imaging systems

Recent progress in the development of MHz frame flow diagnostics are presented, based on enhancements to a "burst" mode Nd:YAG laser. In particular, a PDV system that can measure velocity over a plane at rates up to 1 MHz is demonstrated, as well initial results from a custom-built Optical Parametric Oscillator, designed specifically for use with the burst mode pump. Production of broadly wavelength tunable pulse trains, with order mJ individual pulse energy and order 1 cm/sup -1/ spectral linewidth is described.
