Abstract: An apparatus for generating a short-pulse laser using a temporally modulated sideband gain is provided. The apparatus includes a laser diode and an external reflector. By use of a time difference resulted by a nanosecond laser pulse signal at the external reflector, a sideband gain is obtained for generating a short-pulse picosecond laser output.
