Abstract

We have developed a novel electro-optic Q-switched diode-end-pumped solid slab laser that combines high energy, short pulse width, high repetition rates, and diffraction-limited beam quality. With two partially end-pumped Nd:YLF slabs and a 100mm long off-axis positive branch stable–unstable oscillator, 24.2mJ, 7.1ns electro-optic Q-switched pulse at 1kHz repetition rate with a beam quality of Mx2=1.4 and My2=1.3 was generated. The peak power reached 3.5MW. Efficient external second-harmonic generation was achieved by use of lithium triborate with low peak-power intensity.
