Abstract
The paper mainly focuses on the research of the high-power semiconductor laser signal transmitter. There are two keys in the design: first, the power-driven technology of the high-power semiconductor laser. The paper generates fast current pulse in a low-impedance load by the way of control the pulse length to drive the semiconductor lasers. Second, the information coding techniques based on laser pulses. It is realized in the control of Field-Programmable Gate Array. In additionally, in the optical window design, the system use of inverted telescope lens structure to compress and collimate the laser beam. The specimen achieved the desired performance in experiment.
