All-solid-state tunable ultraviolet subnanosecond laser with direct pumping by the fifth harmonic of a Nd:YAG laser

摘要

We report what we believe is the first all-solid-state tunable ultraviolet laser pumped by the fifth harmonic of a Q-switched Nd:YAG laser. Our laser based on a Ce↑(3+):LiLuF↓(4) active medium stably generates a single, satellite-free, 0.88-ns pulse under 5-ns, 10-Hz repetition rate pumping conditions.A novel tilted-incident-angle side-pumping scheme resulted in a simple laser-cavity design. # 1998 Optical Society of America OCIS codes: 140.3580, 140.3600, 140.3610, 160.3380, 160.4330, 190.0190.
