| چکیده | ||
| In this paper, designing and fabrication of a diode pumped Nd:YAG laser with a new design of laser head and high beam quality factor is reported. Appropriate diode lasers are prepared. Driver circuit, which works at quasi continuous wave (QCW) mode, and has tunable pulse repetition rate and input current, is fabricated. Heat distribution in the active material and output beam profile is simulated by LASCAD software. Output pulses with 14 mJ energy, 200 microseconds time duration, and 1 Hz pulse repetition rate are achieved. High beam quality factor with M2≤1.08 is obtained. | ||
