Abstract:

The program represents an effort to develop a stable, tunable CO2 laser with a tuning range of plus or minus 750 MHz. In order to increase the tuning range of a CO2 laser beyond the 50 to 100 MHz doppler broadening limited value, it is necessary to increase the gain linewidth. The technical approach taken here is to raise the operating laser pressure and thus broaden the gain linewidth. The linewidth broadens at the rate of 5.3 MHzTorr and equals 1500 MHz at 283 Torr. High pressure operation is achieved by operating the laser in the waveguide mode, and thus using a small capillary bore as the gas discharge region.
