ABSTRACT:
Apparatus for mode discrimination in laser applications. A laser operating at a wavelength .lambda.c may have an undesired mode operating at .lambda.e. Mirrors are constructed such that the loss induced in the undesired mode by the wavelength centering of at least one of the mirrors exceeds the available gain of the laser.
