ULTRAVIOLET SUBNANOSECOND PULSE-TRAIN GENERATION FROM AN ALL-SOLID-STATE CE-LICAF LASER

We have directly and passively generated a 290-nm, 600-ps pulse train from a Ce:LiCAF laser pumped by the fourth harmonic of a conventional 10-ns Q-switched Nd:YAG laser. This simple, all-solid-state, short-pul se laser has been realized by employing a recently studied, self-injec tion-seeding pulse-train generation scheme using Ce:LiCAF, a tunable u ltraviolet laser medium.
