Generation of 2.6-mJ 400-kW pulses from a compact Yb:Gd3Ga5O12 laser repetitively Q-switched by an acousto-optic modulator.
An efficient, acousto-optically Q-switched, and compact Yb:Gd(3)Ga(5)O(12) laser oscillating around 1026 nm is demonstrated, producing an output power of 5.15 W at a pulse repetition rate of 2 kHz, with optical-to-optical and slope efficiencies being 35.8% and 52%, respectively. The generated laser pulses are 6.4 ns in duration (FWHM), with pulse energy and peak power amounting, respectively, to 2.58 mJ and 403 kW.
