摘要

报道了一种可调增益开关Cr:forsterite振荡放大器系统的稳定单纵模工作。一种新颖的耦合腔振荡器结构提供了0.3 jcm(-2)的低阈值影响，使系统对低增益或高寄生损耗的激光介质具有吸引力。在受腔光学限制的100 nm波长范围内，获得了具有150 MHz仪器限制带宽的近变换限制脉冲。Cr(4+)浓度范围在3-21 x 10(18)-cm(-3)范围内的forsterite晶体已被用于研究放大器在单通道和双通道配置下的性能。

Pulse amplification of a single frequency Cr:forsterite laser

Stable single-longitudinal-mode operation of a tunable gain-switched Cr:forsterite oscillator-amplifier system is reported. A novel coupled-cavity oscillator configuration provides a low-threshold fluence of 0.3 J cm(-2), making the system attractive for laser media with low gain or high parasitic loss. Nearly transform-limited pulses with instrument-limited bandwidths of 150 MHz have been obtained across a 100-nm wavelength range, limited by the cavity optics. A range of forsterite crystals with Cr(4+) concentration in the 3-21 x 10(18)-cm(-3) range has been used for investigation of amplifier performance in single- and double-pass configurations.
