摘要
With a plano-concave cavity, diode-pumped continuous-wave （CW） and actively Q-switched Nd：YVO4 laser operating at 1.34 #m is demonstrated. Maximum CW output power of 4.76 W and Q-switched average output power of 2.64 W are obtained with output coupler （transmission T = 3.9%）. For the Q-switching operation, the theoretically calculated pulse energy and pulse width, with a pulse repetition frequency （PRF） range of 5-40 kHz, coincide with the experimental results. With a T = 11.9% output coupler, the maximum peak power of 24.3 kW and minimum pulse width of 6.5 ns are obtained when the PRF is i0 kHz. To the best of our knowledge, this is the shortest actively Q-switched pulse duration ever obtained in a 1.3-μm Nd-doped vanadate laser.
