ABSTRACT:
A high pressure, high power, compact laser fabricated from a block of material which is highly transparent at the wavelength of operation. The transmitting block contains a multiplicity of channels along the longitudinal axes thereof, each channel being of such a minute cross-section that a laser medium located within each channel is incapable of independently sustaining a lasing action in a waveguide mode of operation. The multiplicity of channels, in combination, provide sufficient gain for a laser mode propagating within the transmitting material and totality of channels thereby providing an extremely large output from a laser having a minimal cross-sectional configuration.
