Continuously tunable CH3F Raman far-infrared laser.
By pumping CH(3)F with a 150-mJ, continuously tunable, multiatmosphere CO(2) laser, we have produced approximately 0.2-mJ far-infrared laser pulses that can be tuned quasi-continuously over approximately 85% of the range from 220 to 400 microm. The tunable far-infrared laser action results from two-photon (Raman) transitions in the R branch of the CH(3)F nu(3) band.
