ABSTRACT:
A synergistic quasi-free electron laser for generating infrared radiation. The laser includes a means for producing a volume of ionized gas plasma, a means for directing an electron beam through the gas plasma in a first direction, and a means for directing a laser pump beam into the gas plasma in a second direction opposite to the first direction to produce synergistic bunching of the electron beam and the ionized gas plasma. A portion of the laser pump beam is backscattered by the bunched electron beam and gas plasma to form an output beam having a frequency up-shifted from that of the laser pump beam. The frequency of the output beam may be tuned by changing the velocity of the electron beam.
