Abstract
In a stabilized laser system, a an output signal is to be generated having a desired central wavelength. At least one laser, which, while emitting light and having a preselected portion thereof fed back thereto, causes the output signal of the laser 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 processes a first portion of the output signal from each laser and generates a feedback signal having a spectral response peaking at a wavelength shifted in an opposite direction to the first direction generated by each laser. The feedback signal each 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.
