By using xenon flash lamp as pumping light source and BDN dye film as passive Q-switch or KD*P crystal as active Q-switch,we have,for the first time,realized Q-switching run from 1.06μm to 0.53μm in the Nd_(x)Y_(1-x)Al_(3)(BO_(3))_(4)(NYAB)self-frequency doubling laser and obtained MW/cm^(2) giant pulse out-put at 0.53μm wavelength.Meanwhile,the green light output energy and pulse duration were measured under the conditions of different resonator lengths and pumpings.The experimental results are in agreement with the numerical solutions of the Q-switching coupling wave rate equations.Moreover,the ways of improving the green laser output peak power are proposed.
