Abstract

We generated sub-kilowatt peak-power and 6-ps duration 390-nm optical pulses via the fourth harmonic generation of amplified optical output from a gain-switched 1.55-microm laser diode. We obtained a power-conversion-efficiency of 12% from 1.55-microm to 390-nm light, and subsequently applied the ultraviolet pulses to time-resolved spectroscopy of blue-violet luminescent materials, including a Coumarine dye solution and nitride semiconductor materials using single-photon and two-photon excitation schemes.

摘要

我们通过对增益开关型1.55微米激光二极管的放大光输出进行四波混频，产生了亚千瓦峰值功率和持续时间为6皮秒的390纳米光脉冲。我们实现了从1.55微米到390纳米光12%的功率转换效率，随后将这些紫外脉冲应用于蓝紫色发光材料的时间分辨光谱研究，这些材料包括香豆素染料溶液和氮化物半导体材料，采用了单光子和双光子激发方案。
