High repetition rate electrooptically Q-switched Nd:YVO₄ slab laser with high beam quality output

Partially end-pumped slab laser using hybrid resonator is a favourable concept to scale high power with high beam quality in compact dimension. Nd:YVO₄ slab laser has the advantages of large laser cross section and short fluorescence lifetime. These features are required in high repetition rate short pulse length applications. An electrooptically Q-switched slab laser with hybrid resonator has been realized. High repetition rate pulse with high beam quality output is measured. At 5 kHz operation, A Q-switched laser with the pulse energy of 7.2 mJ and the pulse width of 5.7 ns is obtained. The energy and width are 1.6 mJ and 9.5 ns respectively when the repetition rate reaches 50 kHz. The beam quality factor is lower than 2.
