ABSTRACT:
An emedded Bragg grating laser Master-Oscillator and Power-Amplifier (MOPA), includes an optical waveguide which receives and propagates pump light of a predetermined wavelength launched into the optical waveguide; a first master oscillator laser, disposed in the waveguide in the path of the pump light, the laser having a laser cavity disposed between a first pair of reflectors and having a first laser gain medium within the first laser cavity which emits first lasing light in response to the pump light, the first reflectors reflecting a predetermined amount of the first lasing light within the first laser cavity and passing a predetermined amount of the first fusing light as first output laser light from the first laser, the first reflectors passing the pump light through the first laser; at least one of the first reflectors comprises a Bragg grating; and an optical waveguide power amplifier, disposed in the path of the first output laser light and the pump light, and having a first amplifier gain medium therein which emits first amplified laser light in response to the pump light and the first output laser light.
