Abstract

An investigation is made into a quasi-CW (QCW) diode-pumped holographic adaptive laser utilising an ultra high gain (~104) Nd:YVO4 bounce amplifier. The laser produces pulses at 1064nm with energy ~0.6mJ, duration <3ns and peak power ~200kW, with high stability, via self-Q-switching effects due to the transient dynamics of the writing and replay of the gain hologram for each pump pulse. The system produces a near-diffraction-limited output with M2<1.3 and operates with a single longitudinal mode. In a further adaptive laser configuration, the output was amplified to obtain pulses of ~5.6mJ energy, ~7ns duration and ~1MW peak power. The output spatial quality is also M2<1.3 with SLM operation. Up to 2.9mJ pulse energy of frequency doubled green (532nm) radiation is obtained, using an LBO crystal, representing ~61% conversion efficiency. This work shows that QCW diode-pumped self-adaptive holographic lasers can provide a useful source of high peak power, short duration pulses with excellent spatial quality and narrow linewidth spectrum.
