Abstract: | A non-critically phase-matched KTiOPO4 optical parametric oscillator (OPO) intracavity pumped by a laser diode end-pumped acousto-optically Q-switchedNd:YAG laser
is experimentally demonstrated. The highest average power is obtained at the pulse repetition rate (PRR) of around 15 kHz,
which is different from the widely reported Nd:YVO4 laser pumped OPO in which the highest average power is obtained at a very high PRR, e.g. 80 kHz. With an incident laser diode
power of 6.93 W and a pulse repetition rate of 15 kHz, an average signal power of 0.72 W is obtained with a peak power of
7.7 kW and an optical-to-optical conversion efficiency of 10.4%.
