“…Laser-diode-pumped (LD-pumped) solid-state lasers possess the merits of compact structure, high peak power, narrow pulse width, high conversion efficiency, good beam quality, etc., and are widely used in microprocessing, laser ranging, imaging, and space communication. [1][2][3][4][5][6][7] In the particular field of lidar, high pulse energy is conducive to long-distance detection, narrow pulse width and high repetition rate contribute to high resolution and high sampling rate, and high beam quality and stability are favorable for obtaining clear images of targets. 8 At present, to realize pulsed laser output with high repetition rate, Q-switching is mostly utilized.…”

We report a compact and highly stable 1064-nm electro-optic Q-switched laser operating at the repetition rate of 1 kHz. A composite Nd:YAG crystal was used as the gain media and the cavity length was 105 mm. Under the average pump power of 11 W, the output power achieved 2.404 W with the pulse width of 4.558 ns, corresponding to the maximum peak power of 0.527 MW and the optical-to-optical conversion efficiency of 21.85%. The slope efficiency reached 42.69%. The beam quality in the horizontal (M 2x ) and vertical (M 2 y ) directions were 1.81 and 1.58, respectively. The pulse timing jitter was less than 1 ns, and the average power fluctuation measured within 30 min was 0.83% (RMS). It is believed that such a compact and highly stable pulsed laser with high repetition rate, high peak power, and good beam quality has great potential in the fields of lidar, etc.

“…Laser-diode-pumped (LD-pumped) solid-state lasers have a wide application in the fields of material processing, laser ranging, and laser imaging because of their compact structure, high efficiency, good beam quality, high reliability, and long service life [1][2][3][4][5]. LD operates in both continuous waves (CW) and quasi-continuous waves (QCW) [6].…”
