Monopulse Lasers Based on Yttrium Aluminum Garnet with Neodynium Ion with Resonators Based on an Optical Circuit of a Four-Pass Amplifier with Transverse Diode Pumping

The results of application in monopulse lasers based on yttrium aluminum garnet resonators with Nd 3+ ions based on the optical scheme of a four-pass amplifier with one-sided lateral pumping of the active element by monospectral laser diode arrays are presented. The proposed resonator schemes make it possible to increase the output energy of single pulses of laser radiation. Monospectral gratings with efficient heat removal from laser diodes are capable of ensuring the operability of lasers with an increase in the repetition rate of monopulses and an expansion of the ambient temperature range.
