An active-passive double Q-switched 946nm laser was reported which with a double 45°cutmagnesium oxide doped LiNbO_3electro-optic crystal and a monolayer molybdenum selenide saturable absorber.In order to obtain 946nm laser pulses with high energy and high peak power,apulsed laser diode side-pumped long Nd∶ YAG rod is used as the gain medium in a folded biconcave cavity.Output pulses with maximum pulse energy and peak power up to 3.15 mJ and 346kW were obtained, corresponding to 550Hz repetition rate and 9.1ns pulse duration at 946nm.Peak to peak instabilities of pulse width and pulse energy were±2.87%and±3.42%,beam quality factors were M_x~2=3.851and M_y~2=3.870. |
