By using xenon flash lamp as pump source and Cr4+:YAG as passive Q-switcher, we have performed the Q-switched laser operation at 1.06μm with an Nd3+:NaY(WO4)2 (known as Nd:NYW) crystal. Meanwhile, the pulse width, the single pulse energy and the repetition rate under different small-signal transmissions of Cr4+:YAG and different reflectivities of output reflector are measured, and the numerical solutions of the coupling wave rate equations agree with the experimental results.
