System for, and method of, regulating the wavelength of a light beam

摘要: A laser light beam is processed in a first optical path to produce indications plurality of free spectral paths. These are introduced through slits signals at spaced positions the opposite peripheries linear detector array. The distances between correlated pairs energized detectors array indicate relative value wavelength ranges. also second path, simultaneously with processing single path. dependent upon beam. produced may be another slit energize centrally disposed particular light. scanned related time disposition data system processes these and produces signal adjust value. When pulsed, described above operate real after each pulse before next wavelength.
