【Abstract】 An optically pumped far infrared methanol laser with a hollow dielectric waveguide resonator of 1.2m long has been developed at the National Institute of Metrology. A power of 50mW CW is achieved for 70.5μm line when the CO2 pumping power is about 22W. The conversion efficiency of infrared cavity can reach 8.4% of the theoretical maximum. This laser is suitable for the harmonic mixing experiments.更多还原
