Diode-pumped alkali lasers (DPALs) have been developed in the recent years for their high Stocks efficiency, good beam quality, compact size and near-infrared emission wavelengths. Dividing a cylindrical vapor cell into many cylindrical annuli, we first obtain parameters such as the population density distributions, transition rates of pump photon absorption, and transition rates of laser photon emission...
An end-pumped configuration is one of the most common laser structures at present. The filling factor provides the great effects on the laser performances, i.e., laser power, beam quality, pulse width, and output stability of an end-pumped laser. In this report, we systematically analyze the absorption characteristics, output power, and optical-optical efficiency by using a segmental accumulation...
Diode-pumped alkali lasers (DPALs) have undergone rapid development to become one of the most promising candidates for use as high-power laser sources in recent years. Relaxation oscillation (RO) is a common phenomenon related to the dynamic process in the time domain. Sometimes, it is applied in parameter measurement, but sometimes it should be eliminated to ensure stable output. In this paper, we...
