The optically pumped rare gas laser (OPRGL) is a new type of optically pumped gas laser with high quantum efficiency, which can convert the high output power of a diode laser into the output power of a gas laser with high beam quality. In [1], the first generation on inert gases was demonstrated. According to published open sources, there has been a serious step in the world in studying the properties of the active medium on the model of a laser source based on a mixture of rare gases with optical pumping. The discharge was optimized and became stable at atmospheric pressure [2,3]. Results of measurement of laser output power on mixture of inert gases with optical pumping (OPRGL) are presented. An experimental gas mixture consisting of 98% Ne (buffer gas) and 2% Ar was used as the active medium. The main registered parameter of the experiments was the generation power, which was measured by an optical calorimeter. Variable parameters in experiments were: pressure and flow rate of the gas mixture in the discharge chamber, reflection of the output mirror of the (flat) optical resonator, repetition rate of discharge pulses. Laser generation at a wavelength of 912 nm was obtained and the generation power level was investigated depending on the experimental setup parameters. The maximum value of the obtained lasing power was 110 mW.
