Abstract

Apparatus and method for generating continuous wave 16 ..mu..m laser radiation using gaseous CF/sub 4/. Laser radiation at 16 ..mu..m has been observed in a cooled static cell containing low pressure CF/sub 4/ optically pumped by an approximately 3 W output power c-w CO/sub 2/ laser. The laser cavity employed was a multiple-pass off-axis-path two spherical mirror ring resonator. Unidirectional CF/sub 4/ laser output power at 615 cm/sup -1/ exceeded 2 mW. Computer calculations indicate that for modest pump powers of about 40 W, approximately 1 W of emitted laser radiation at 16 ..mu..m might be obtained.

Patent Telle, J.M.

An apparatus is described for generating cw 16 ..mu..m laser radiation in gaseous CF/sub 4/, which comprises in combination; a. a cw pump laser for generating coherent radiation in the 9 ..mu..m region of the infrared spectrum, the coherent 9 ..mu..m radiation having a wavelength appropriate for interacting with the CF/sub 4/ such that a relationship between pump power and CF/sub 4/ pressure results in a population inversion in the CF/sub 4/ suitable for producing cw laser oscillation therein; b. means for directing the coherent 9 ..mu..m radiation into the region of the CF/sub 4/ in order to permit themore »« less
Apparatus and method for generating continuous wave 16 .mu.m laser radiation using gaseous CF.sub.4

Patent Telle, John M. (Los Alamos, NM)

Apparatus and method for generating continuous wave 16 .mu.m laser radiation using gaseous CF.sub.4. Laser radiation at 16 .mu.m has been observed in a cooled static cell containing low pressure CF.sub.4 optically pumped by an approximately 3 W output power cw CO.sub.2 laser. The laser cavity employed was a multiple-pass off-axis-path two spherical mirror ring resonator. Unidirectional CF.sub.4 laser output power at 615 cm.sup.-1 exceeded 2 mW. Computer calculations indicate that for modest pump powers of about 40 W, approximately 1 W of emitted laser radiation at 16 .mu.m might be obtained.

Continuous wave 16. mu. CF/sub 4/ laser

Journal Article Telle, J. - IEEE J. Quant. Electron.; (United States)

A 16 ..mu.. CF/sub 4/ laser oscillator has operated continuous wave in a cooled static cell. Pump powers required from the low-pressure continuous wave CO/sub 2/ laser were approximately 3 W. The laser cavity was a multiple-pass off-axis-path two-mirror ring resonator. Unidirectional CF/sub 4/ laser power at 615 cm/sup -1/ exceeded 2 mW. Rate equations were used to estimate scaling of this laser source. For modest pump powers (40 W) approximately 1 W of emission power is predicted from this small and simple system.

Generation of 14. mu. M and 16. mu. M laser radiation from a CO/sub 2/ gas laser

Patent Plesance, L.D.

Described is a technique for generating 16 ..mu..m laser radiation from a CO/sub 2/ molecular gas laser system by use of the 02/sup 0/0-01/sup 1/0 vibrational transition of CO/sub 2/. The technique employs a system for pumping the CO/sub 2/ molecules from the ground state to the 00/sup 0/1 vibrational energy level such that a population inversion is created between the 00/sup 0/1 and 02/sup 0/0 energy levels, and transferring the population of CO/sub 2/ molecules from the 00/sup 0/1 level to the 02/sup 0/0 vibrational energy levels by stimulated emission in a time less than the collisional deactivation timemore »« less

Patent Krupke, W.F.

A method and apparatus for producing coherent radiation in CO/sub 2/ vibrational-rotational transitions at wavelengths near 14 and 16 microns are described. This is accomplished by passing a mixture of N/sub 2/ and Ar through a glow discharge producing a high vibrational temperature in the N/sub 2/, passing the excited N/sub 2/ through a nozzle bank creating a supersonic flow thereof, injecting the CO/sub 2/ in the supersonic flow creating a population inversion in the CO/sub 2/, and directing the saturating pulse of radiation near 10.6 or 9.6 microns into the excited CO/sub 2/ creating a population inversion producing coherentmore »« less
