Abstract
A mode-locked C02 laser with transverse pulse pumping has been developed which employs a Ge ultrasonic diffraction cell as an active loss modulator. This report describes the first stage of an effort to exploit the broad bandwidth (5 GHz) of the C02 laser transition and the high concentration of active gas at atmospheric pressure for generating ultrashort infrared pulses at 10.6 m wavelength. With the laser system described herein, output pulses with typical durations of about 1 nanosecond and peak powers in the multimegawatt range have been obtained for the first time.
