Abstract
An adjustable etalon mode selector is mounted within the optical cavity of a laser and includes a pair of spaced prisms mounted along the optical axis of the cavity with the laser beam passing therethrough and means for selectively adjusting the spacing between the prisms in a manner such that the resonant frequency of the laser cavity and etalon combination remains constant during the adjustment of the prism spacing in order that a particular mode of the operating wavelength spectrum of the laser may be selected for output, without the adjustment modulating the cavity natural resonant frequency.
