Abstract

Diode-pumped alkali lasers (DPALs) have gained rapid development in the recent years due to their great potential for realization of high-power lasers. Relaxation oscillation (RO) is a common phenomenon related to the dynamic process in time domain. Generally, the generation of spikes in RO may affect the output stabilization of a DPAL. In this paper, we develop a kinetic model to investigate the output characteristics in time domain. Using such a mathematical model, a comparative study on the RO features of a diode-pumped rubidium vapor lasers (DPRVL) and a diode-pumped cesium vapor lasers (DPCVL) is theoretically carried out with different physical parameters including the cell temperature, buffer gas pressure, pumping power and reflectance of an output coupler. The analyses should be valuable for design of a steady high-powered DPAL.
