Laser-locking using a phase-shifted volume Bragg grating

Phase-shifted Bragg gratings operate as a Fabry-Perot cavity to facilitate a narrow-band transmission line within the diffraction band of the grating. Such elements, when holographically encoded into a volume element, enable a host of technologies to become available in free-space regimes. Recent advances in PTR glass, a high-resolution medium used for the recording of volume Bragg gratings, have realized higher transmission efficiencies, allowing these elements to be used as a cost-effective laser-locking solution. Here, such a system is investigated, and future configurations are considered.
