The microwave generation technique by optical heterodyning of two slave lasers was optimized considering the sideband peak power of the master laser. Conversion efficiencies higher than 50% were obtained. The use of high performance lasers in the control station may substantially lower costs since no active components must be installed in the base stations, specially microwave amplifiers. Finally, varying the modulation frequency and modulation depth, a continuously wide range of RF frequencies can be obtained, up to the terahertz region.
