Additional cw FIR laser lines from optically pumped CH_2F_2

Abstract

Twenty-five new, cw, FIR lines from CH(2)F(2), optically pumped by a CO(2) laser, have been found, using a variablecoupling, open-structure resonator. Accurate wavelength measurements have been made on the 47 known CH(2)F(2) lines. The new lines are fairly uniformly distributed over a wide range, from 105 to 1448 microm.
