Abstract

We demonstrate an efficient CH₃F oscillator based on an anti-reflection coated Ge dichroic beam splitter. When pumped by the 10R32 line of a CO₂ laser (10.17 μm), 0.81-mJ far-infrared laser is obtained with the wavelength of 192 μm. The energy conversion efficiency of 0.16 % is the highest for an optically pumped 192-μm laser system to our knowledge. The beam quality factor of (Formula Presented.) and (Formula Presented.) is 1.53 and 1.57, respectively. Further, this oscillator can be extended to optically pumped far-infrared lasers with various wavelengths.
