Abstract

Abstract A new scheme of diode pumped alkali vapor laser (DPAL) which uncouples the temperature and the concentration of alkali vapor is reported. Non-equilibrium instead of saturated potassium vapor is used. The calculation results indicate that the optical-to-optical efficiency of the diode pumped non-equilibrium potassium vapor laser (NE-DPAL) is higher than that of saturated vapor at high power pumping density.
