Abstract
Physical condition is developed to achieve single-pulse emission with the uniform repetition rate of the PQS microchip lasers thereby overcoming the irregular pulse train formation with QCW pumping. Single-pulse with the high energy of 3.76 mJ at 50 Hz is obtained in Nd:YAG/Cr:YAG monolithic microchip laser without higher-order transverse modes in room temperature. The presented physical condition can provide a good method to design PQS microchip lasers to emit single-pulse at single transverse mode operation for different wavelengths and laser materials.
