Title: Submillimeter laser and Fabry-Perot spectroscopy using metallic mesh. Annual technical report No. 2, 1 June 1979-31 May 1980

Abstract

An optically pumped submillimeter laser has been designed and the laser resonator constructed. The objective was to produce a laser which could accommodate a wide range of waveguides and output coupling forms, yet still retain consistent performance over the whole range from 40 micrometers to 1.2 mm. The performance expected was a large number of emission lines over the described range with output powers in excess of 1 mW. Experience from other submillimeter laser systems used led to the choice of a 25 mm I/D dielectric waveguide with a 5 mm diameter pinhole type output coupler as the basis of the optical resonator. A novel mirror translator system, in the form of a 'wobble stick', has been designed and successfully operated in the laser. Such power levels as described were ahcieved using the CO/sub 2/ pump laser described in the 1st Annual Technical Report. A two element Low Pass Blocking Filter which was designed and constructed for use in conjunction with the submillimeter laser has been successfully applied to help identify the 170.6 micrometers emission line from CH/sub 3/OH pumped with 9P36 CO/sub 2/ transition. The more powerful 118.8 micrometer emission line was effectively blocked, although still lasing, since themore » filter was external to the laser cavity.« less
