Abstract :
Tunable IR signals can be generated by the proposed arrangement comprising a CO2 laser and a tunable millimeter-wave cavity coupling modulator. The position of the modulator within the laser cavity was found to be critical but can be optimized. Under optimum conditions, 2.5 mW (8.0 mW) can be expected in each sideband with 1-W drive power for GaAs (CdTe) crystals at bandwidths of 21 GHz (10 GHz). The design principle of the millimeter-wave cavity was verified in a scaled-model experiment.
