MILLIMETER AND SUBMILLIMETER DEVICE RESEARCH.

Abstract

The construction of two HCN lasers is described. These lasers, operating in the submillimeter wavelength region, have been used for linewidth and stability investigations. Laser oscillations have been observed for H2O at 118.65 microns wavelength. The HCN lines at 337 microns and 311 microns have been observed and beat against phase-locked harmonics of a 5 MHz frequency standard. A linewidth of approximately 280 kHz has been measured for the 337 micron line. Variations of the laser parameters have been made to observe the effect on laser action. One of the HCN lasers is being prepared for experiments on locking the laser to a frequency standard. Terminating investigations on the H2S millimeter wavelength molecular beam system as a frequency standard are discussed.
