Generation of ultrashort 25-μJ pulses at 200 nm by dual broadband frequency doubling with a thin KBe2BO3F2 crystal.

Abstract

Ultrashort pulses with a 25-μJ output energy were generated at 200 nm by dual broadband frequency doubling with a thin KBe(2)BO(3)F(2) (KBBF) crystal at 1 kHz as the fourth harmonic of a high power Ti:sapphire laser. The spectrum was broadened to a spectral width of 2.25 nm. The pulse duration of 56 fs was measured by single-shot autocorrelation with two-photon fluorescence from self-trapped excitons in a CaF(2) crystal.
