摘要： A planar laser gain medium (30) and laser system (100). The laser gain medium (30) includes an active core (32) having a high aspect ratio cross-section with a fast-axis dimension and a slow-axis dimension, signal claddings (36, 38) adapted to form reflective boundaries at fast axis boundaries of the core, and a material (50, 52) adapted to minimize reflections at slow axis boundaries of the core. In the illustrative embodiment, the laser gain medium (30) is an optical fiber. The core (32) and signal claddings (36, 38) form a waveguide adapted to control modes propagating in the fast-axis direction. When the laser gain medium (30) is employed as a laser oscillator, a high reflectivity mirror (102) and an outcoupler (104) are positioned at opposite ends of the core (32) to form a laser resonator adapted to control modes in the slow axis direction.

摘要： 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.

摘要： A phase conjugate mirror (10) comprising a photonic band gap light guide (30) and a stimulated Brillouin scattering medium disposed in operational relation thereto. In specific embodiments, the light guide is an optical fiber (30) with a high index cladding transparent at a propagation wavelength and a hollow or solid core (32'). The cladding (34') is microstructured silica and supports guide modes through frustrated tunneling photonic band gap guidance or Bragg photonic band gap guidance. The fiber has an array of channels (36') disposed around the core. In one embodiment, the fiber is disposed within a stimulated Brillouin scattering cell (20). In this embodiment, the medium is gas, gel, or liquid. In an alternative embodiment, the medium is a solid disposed at the core of the fiber (130). The invention provides a means of guiding light with a gas filled or solid core structure with high guiding efficiency, high reflection back into the medium, without disturbing the polarization state of the light as it propagates.
