Abstract
A pulsed laser light source for producing amplified light pulses is provided. It includes a three-port optical circulator connected to a first, second, and third waveguide branch, a seed module for generating a pulsed light and propagating the light along the first waveguide branch to the first port of the optical circulator and out the second port to the second waveguide branch, a reflector in the second waveguide branch for reflecting the light back through the second port of the optical circulator for circulation out the third port to the third waveguide branch, and a light output provided in the third waveguide branch for outputting the amplified light pulses. An amplifier is disposed in the second waveguide branch between the optical circulator and the reflector for amplifying the light and an optical modulator operable for modulating the pulsed light is disposed in the third waveguide branch.
