飞秒光学参量振荡器(OPO)能产生从紫外到中远红外波段的可调谐飞秒激光脉冲,在频率计测、生物医学、大气探测、宽带通信及**等领域有着广泛的应用。对飞秒钛宝石激光器同步抽运OPO进行了研究,相继实现了波长稳定在1053 nm的高功率飞秒OPO运转。在此基础上,进一步研究了高功率掺镱全固体飞秒激光器同步抽运OPO。结合国内外飞秒OPO的研究进展,对未来全固态飞秒激光器同步抽运OPO的发展进行了展望。

Femtosecond optical parametric oscillators (OPOs) are capable of generating tunable femtosecond laser pulses in the ultraviolet, mid- and far-infrared spectral range. These oscillators are widely used in the fields of frequency metrology, biomedicine, gas detection, broadband communications, and defense. This study conducts the research on the OPO synchronously pumped by a femtosecond Ti:sapphire laser, and realizes the operation of high-power femtosecond OPOs with a stabilized wavelength of 1053 nm. Based on these, the OPOs synchronously pumped with high-power femtosecond Ytterbium-doped all-solid-state lasers are further investigated. With the relevant research progress on femtosecond OPOs worldwide, the future development of OPOs synchronously pumped by all-solid-state femtosecond lasers is prospected.
