“…The utilization of a Q-switch can enable the laser to consider the output requisites. Compared with passively Q-switched (PQS) ones, actively Q-switched (AQS) lasers have the advantages of faster switching, better hold-off ability, more considerable output energy, and controllable repetition rates [7,12,13]. Among various active Q-switching methods, electro-optical (EO) Q-switching is a competitive and practical option.…”

In a side-pumped laser module, we simulate the pumping power distribution across the cross-section of Nd:YAG rods at varying diameters. The coupled rate equations with the spatial overlap efficiency for a four-level actively Q-switched side-pumped laser are considered complete. After a Q-switched pulse terminates, the expressions of laser output parameters are derived. We assess the single pulse energy, pulse width, and peak power using the analysis function. The 200 Hz Q-switched side-pumped Nd:YAG laser with a peak power of 103 kW and beam quality factors M2 = 1.67 is developed to the validity of theoretical models.

“…Hence, the volume of AQS lasers can be further compressed. In addition, periodic pulse pumping with short pumping durations and high pumping outputs can considerably mitigate the thermal effect in side-pumped lasers [9][10][11][12][13].…”
