Compact 24-kHz copper-laser-pumped Ti:sapphire laser

A compact, pulsed Ti:sapphire laser producing 320 mW of average power at a 24-kHz repetition rate has been demonstrated, with the output pulses having 50-ns-width and 440-W peak power. Use of a novel small-scale copper laser as the pump source results in high-efficiency, short-pulse operation without a Q switch, with excellent pulse-to-pulse amplitude stability.
