Abstract:

1 OPTICAL PUMPING IN DARK RUBY Attempts were made to get maser action in the submillimeter region by incoherent optical pumping in a solid. The absorption of thermal noise power in a microwave resonator by an appropriate crystal therein is regarded as capable of changing the fluorescent intensity in the crystal. The terminal level of the fluorescent line must be one of the levels between which there is microwave absorption. 2 HARMONIC GENERATION IN HCN BY MULTIPLE QUANTUM CONVERSION A traveling wave interaction in a 2.5-meter section of RG 96U waveguide containing HCN gas produced a peak power at 104.1 Gc of 1.8 watts. 3 SUBMILLIMETER-WAVE SPECTROSCOPY A submillimeter wave monochromator was designed and constructed that is capable of covering the spectral region from 100 microns out to about 2.5 mm in wavelength. 4 MIXING OF LASER LIGHT IN A BULLK PHOTOCONDUCTOR. Beat notes of 3 Gc were detected on production by Fabry-Perot mode frequencies of a laser when mixed in a bulk photoconductor and compared with previous results.
