| Abstract: | A laser diode (LD) driven by a DC bias and superposed pulse current is used as the pump source. A F-P laser composed of a Nd~(3+)∶YVO_4 crystal is end-pumped by the LD. Using the gain-switching technique, the output pulse width can be changed with the amplitude and pulse width of (LD's) driven current. The repetition rate of output laser can be exactly controlled by pumping repetition rate. A compact, all-solid-state short-pulse laser with stable single mode output and controllable high repetition rate is obtained. It can act as an ideal pulsed seed source and be applied in many fields, for instance, laser ranging, LIDAR and etc. |
