HIGH EFFICIENCY SINGLE AND MULTIPLE WAVELENGTH STABILIZED LASER SYSTEMS

摘要

In a stabilized laser system (50), a signal is to be generated at an output thereof having a desired wavelength. At least one laser (51), which emitting light and having a pre-selected portion thereof fed back thereto, causes the output signal of the at least one laser source to be shifted in wavelength in a first direction which is spaced apart from the center wavelength of the fed back signal. A feedback generating arrangement (54) is coupled to the at least one laser to process a first portion of the output signal from the laser and generate a feedback signal having a spectral response peaking at a wavelength shifted in an opposite direction to the first direction generated laser. The feedback signal causes the laser to provide an output signal at the output of the stabilized laser system having a spectral response that peaks essentially at the desired wavelength.
