Abstract

A high-power 588 nm light produced by an intracavity frequency-doubling acousto-optic Q-switched self-frequency Raman laser is reported. A 20 - mm -long Y V O 4 Nd : Y V O 4 composite crystal and a 15 - mm -long Li B 3 O 5 (LBO) with noncritical phase-matching ( θ = 90 ° , ϕ = 0 ° ) cut were adopted for efficient self-Raman laser operation and second-harmonic generation, respectively. By the optimizing the focus position of incident pump light and Q-switch repetition rate, yellow light with 5.7 W average power was generated under the pump power of 23.5 W , corresponding to the overall diode-yellow conversion efficiency of 24.2% and slope efficiency of 32%. The pulse width is about 16 ns , and the pulse energy is up to 95 μ J .
