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 long off-axis positive branch stable–unstable oscillator, , electro-optic Q-switched pulse at repetition rate with a beam quality of and was generated. The peak power reached . Efficient external second-harmonic generation was achieved by use of lithium triborate with low peak-power intensity.
