Gordon Developed.  This 2-inch gas laser has been used as a swept frequency oscillator in an optical heterodyning experiment. By varying the spacing between the end mirrors of the laser cavity, he can tune the device to oscillate at a single frequencey within a 1500 mc range centered at 4.73 x 10-14 cps.
