In order to obtain integrative ns-pulsed solid-state laser,a Cr~(4+)∶YAG passively Q-switched laser was designed,which combined Cr~(4+)∶YAG with Nd∶YAG by the aid of thermal bonding,and whose F-P laser cavity was composed by coating films on its both sides.The quasi-continuous laser pulse output was realized in the experiment by directly pumping the crystal from its end by the fiber coupled laser diode.The pulse width (5.3 ns) was obtained by the p6703A photo-detector.A radiator was designed to eliminate the thermal lens effect existing in the experiment.The contrast of the air blowing and the radiator was implemented.The experiments approves that the design is feasible and the laser works well.
