ABSTRACT:
A tunable pulsed laser includes a seed source and an optical circulator. The optical circulator includes at least a first port coupled to the seed source, a second port, and a third port. The laser also includes an amplitude modulator characterized by a first optical side and a second optical side. The first optical side is coupled to the second port of the optical circulator. The laser further includes a first optical amplifier characterized by an input end and a reflective end. The input end is optically coupled to the second side of the amplitude modulator. The laser additionally includes a tap coupler optically coupled to the amplitude modulator and characterized by a pre-determined split ratio. Moreover, the laser includes a first photo-detector optically coupled to the tap coupler and adapted to receive a portion of the seed signal transmitted through the amplitude modulator and to generate an output signal.
