Abstract

We originally utilize a nearly hemispherical cavity to accomplish the energy scale-up for a high-repetition-rate nanosecond pulsed pumped Nd:YLF laser passively Q-switched by the Cr4+:YAG saturable absorber. This compact laser is able to efficiently generate pulse energy as large as 1.38 mJ and pulse width as short as 5 ns under a pulse repetition rate of 100 Hz. Further employing the developed Nd:YLF laser to perform extracavity harmonic generations, the maximum pulse energies of 490 μJ at 527 nm and 360 μJ at 351 nm are achieved with the shortest pulse duration of 4 ns.
