Abstract
An automated laser wavelength selection system and method. The system comprises a laser including a lasing medium having an output spectrum characterized by a plurality of discrete spectral lines, an adjustable wavelength selector disposed within and optically coupled to an optical cavity of the laser, a detector optically coupled to the laser to measure the power of light output from the laser, and a processor electronically coupled to the detector and to the wavelength selector. The processor adjusts the wavelength selector through a series of discrete steps and receives a power measurement from the detector at each of the steps. The processor performs statistical analyses on the power measurements, and, based on the statistical analyses, the wavelength selector is adjusted to selectively pass a wavelength that approximately corresponds to a peak of a desired spectral line.
