Abstract :
Power scaling end-pumped Nd:YV04 lasers is difficult due to thermally induced crystal fracture and thermal aberrations. Side-pumping a laser enables power scaling, but typically has issues associated with obtaining both good beam quality with high extraction efficiency. Achieving both of these characteristics at low average power, a Nd:YV04 laser using a total internal reflection (TIR) bounce cavity has been reported. Recently, excellent extraction efficiency and beam quality were achieved using the TIR bounce cavity design with a high peak power diode-pumped Cr:LiSAF laser. In the work we describe a diode pumped Nd:YV04 laser system using a TIR bounce oscillator/amplifier configuration producing high extraction efficiency and good beam quality.
