Abstract:
1. An optical cavity comprising: an entrance aperture for receiving frequencies of input light from a laser, said entrance aperture adapted to restrict the spatial extent of the input light, whereby the input light becomes restricted input light after interacting with the entrance aperture; collimating optics disposed to receive the restricted input light, said collimating optics capable of collimating the restricted input light, whereby the restricted input light becomes collimated light after interacting with the collimating optics; a Brewster angle optical wedge disposed to receive the collimated light, said wedge comprising a semiconductor material, whereby the collimated light becomes imaged light after interacting with the wedge; focusing optics disposed to receive the imaged light, whereby the imaged light becomes output light after interacting with the focusing optics; and reflective optics disposed to receive the output light, said reflective optics adapted to allow pre-selected wavelengths of the output light to pass outside the optical cavity and to reflect all other wavelengths of the output light back into the optical cavity said reflective optics comprising: an output light spatial and spectral array which selects output light frequencies using an output focal plane and a fiber array; and an electronically operated mirror array which returns all other dispersed frequencies to the cavity.
