ABSTRACT:
A coherent optical detector has increased sensitivity for detecting a coherent optical signal by applying the coherent optical signal to be detected to a solid non linear medium pumped by two optical signals of opposite directions and coming from an auxiliary laser. The signal to be detected gives rise to an amplified signal applied with an auxiliary optical signal from the auxiliary laser, to a detector for causing these two optical signals to beat and detecting the beat and so the signal to be detected.
