Abstract

We report on a high-repetition-rate, high-peak-power, linear-polarized 473nm blue laser. A high-power 946nm fundamental laser was obtained based on a diode-pumped acousto-optically (AO) Q-switched Nd:YAG laser using a thermal-compensating resonator and a microchannel heat sink for thermal dissipation. A pulsed 473nm laser was generated using a BiB3O6 (BiBO) crystal as an extracavity frequency doubler. The highest peak power of a 16.7kW blue laser was obtained at a pulse repetition rate of 10kHz with a pulse width of 9ns. Stable operation of the pulsed blue laser can even reach 50kHz.
