Simultaneous stimulated emission at two submillimeter frequencies with parallel polarization was achieved for the first time in a waveguide electric-discharge HCN laser (lambda/sub 0/ = 337 ..mu..): higher modes (TE/sub 01/+EH/sub 21/)/sub q/ and (TE/sub 02/+EH/sub 22/)/sub q/-1 were generated in a resonator free of phase anisotropy. The frequency interval between these modes varied continuously from approx.50 kHz to approx.3 MHz. Moreover, simultaneous emission of two linearly polarized mutually orthogonal modes was observed for the first time in a waveguide HCN laser in which the exit mirror was in the form of two parallel wire gratings with orthogonal directions of the wires. Simultaneous emission of three frequencies was also observed for this laser.
