Tunable electro-optic modulators for laser radar applications - Experimental results

A tunable electro-optic single sideband modulator having a configuration consisting of a CdTe crystal surrounded by a ferrite placed inside a microwave waveguide can be used as a laser local oscillator to track the target translational Doppler frequency in a CO2 laser radar return. Results on measurements to determine the phase velocity matched bandwidth for the above composite modulator configuration are reported.
