High power laser with tuning and line narrowing capability
Patent
·
OSTI ID:6506774
The cavity of a high power laser is selectively tuned to oscillate in a relatively narrow spectral region by placing inside the cavity a birefringent kd*p filter at the Brewster angle. The degree of phase retardation introduced by the filter is controlled by applying an amplitude-variable voltage across the filter or rotating the filter about its beta axis. The laser may thus be line-narrowed and tuned, and may be used to generate two coherent signals at different wavelengths without need for an additional resonant cavity.
