“…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]. A solid-state laser pumped by a QCW LD has higher output power and optical-to-optical conversion efficiencies than that pumped by a CW LD.…”
