摘要
The first Potassium Diode Pumped Alkali Laser (DPAL) with flowing gain medium in closed cycle system has been demonstrated. A slope efficiency of 31% for continuous wave operation was achieved with a maximum output power 5 W. The flow loop was operated with a helium buffer gas pressure of 800 Torr and an alkali metal temperature of 185 degrees C. An examination of laser performance vs flow speed demonstrated higher efficiencies with increasing flow speeds.
