Abstract

We report on a cavity-dumped Q-switched ${\mathrm{TEM}}_{00}$ $\mathrm{Nd}:\mathrm{Y}\mathrm{V}{\mathrm{O}}_4$ oscillator offering a unique combination of high power, constant short pulse duration, and high repetition rate, suppressing the gain dependence of pulse duration in classical Q-switched oscillators. Its performance is compared with that of the same oscillator operated in a classical Q-switched regime, demonstrating the much higher peak powers achievable with this technique, especially at high repetition rates. Up to $31\mathrm{W}$ of $532\mathrm{nm}$ green light was generated by frequency doubling in a noncritical phase matched LBO crystal, corresponding to 70% conversion efficiency.
