System and method for the real-time conversion of two-color incoherent or coherent light to two-color coherent light

摘要

A system and method are described for the real-time conversion of a two-color optical input into coherent light of two colors. The system includes a first electrooptic device oriented to receive the optical input, the device having applied thereto a periodic voltage producing an electrical field periodically varying between magnitudes effective to block one or the other color of the optical input. The system further includes a second electrooptic device oriented to produce coherent light of two colors, this device having applied thereto a second periodic voltage in synchronization with the first-mentioned voltage to produce an electrical field periodically varying between magnitudes effective to block one or the other color of the coherent light source. A gate applies the second periodic voltage to the second electrooptic device only when light of either of the two colors is outputted by the first electrooptic device.
