Abstract

A high-power optically-pumped vertical-external-cavity surface-emitting laser (VECSEL) generating 10.5 W of cw output power at 615 nm is reported. The gain mirror incorporated 10 GaInNAs quantum wells and was designed to have an emission peak in the 1230 nm range. The fundamental emission was frequency doubled to the red spectral range by using an intra-cavity nonlinear LBO crystal. The maximum optical-to-optical conversion efficiency was 17.5%. The VECSEL was also operated in pulsed mode by directly modulating the pump laser to produce light pulses with duration of ~1.5 µs. The maximum peak power for pulsed operation (pump limited) was 13.8 W. This corresponded to an optical-to-optical conversion efficiency of 20.4%.

摘要

报道了一种高功率光泵浦垂直外腔面发射激光器（VECSEL），其在615nm处产生10.5W的连续输出功率。增益镜包含10个GaInNAs量子阱，设计发射峰在1230nm范围内。通过腔内非线性LBO晶体，基频发射被倍频至红色光谱范围。最大光光转换效率为17.5%。该VECSEL还通过直接调制泵浦激光器以脉冲模式运行，产生持续时间约为1.5µs的光脉冲。脉冲运行（泵浦限制）的最大峰值功率为13.8W。这对应于20.4%的光光转换效率。
