Monolithically integrated master oscillator/power amplifiers have been fabricated with a single‐mode distributed Bragg reflector laser as the oscillator and a chain of amplifier output couplers defined by a single‐mode waveguide gain region and a second‐order grating detuned from the gain peak. The output of the amplifier chain is a single frequency and can be phased to obtain a diffraction‐limited output up to an output power of 485 mW.
