Mode locking and efficient generation of pulsed difference-frequency radiation in two-color heterolasers
Efficient schemes are proposed for generation of picosecond pulses in the mid/far-IR and THz ranges through intracavity nonlinear mixing of fields generated in two-color injection heterolasers, operating in the mode-locking regime at room temperature. It is shown that these schemes make it possible to increase the peak lasing power by a factor of about 100.
