ABSTRACT:
An intracavity frequency-modified laser of improved amplitude stability is obtained through the use of a plurality of nonlinear optical crystals within the laser cavity. Extremely low noise operation of such a multiple crystal laser is achieved by measuring the noise in its output radiation as a function of the temperature of its optical cavity and maintaining the cavity temperature at a value that results in low noise production during subsequent operation.
