| Abstract: | In this paper, a new kind of all solid state semiconductor laser pump-probe source was presented which was based on the principle of gain switch. By the control of direct current (DC) and radio frequency (RF) current applied to the source, two train pulses were made which had the repeat frequency of 1 GHz, pulse width of 50 ps and the delay time between two train pulses of around 200 ps. |
