ABSTRACT:
An outcoupler having a wavelength selective, angle sensitive element or Bragg grating and an arrangement for maintaining the element in a predetermined orientation relative to an incident beam of electromagnetic energy. The Bragg grating may be reflective or transmissive. The inventive outcoupler may be used to implement a phase conjugate master oscillator power amplifier with an oscillator; a resonator in operational alignment with the oscillator; and an outcoupler in alignment with the oscillator. In the best mode, second and third Bragg gratings are included within the oscillator and the resonator, respectively.
