Abstract:

Research is described on an experimental program to generate short pulses at the 10.6 micrometers wavelength, to study the propagation and interaction of these pulses with amplifying and absorbing media, and to investigate flowing metal vapor lasers as sources of radiation in the blue-green portion of the spectrum. The selection of a single pulse from a train of mode- locked CO2 laser pulses based on the attenuation and reflection of a gas breakdown has been explored. Work with several low temperature metal vapor lasers, led to the practical design for copper vapor laser operation using fast closed-cycle transverse vapor flow.
