ABSTRACT:
A method for seeding and stabilizing an optical device, wherein the optical device includes one of a continuous wave laser, a pulsed laser, and a parametric system, the method including seeding the optical device with a seed signal, generating a feedback signal from an output of the optical device, and adjusting a wavelength of the seed signal to maintain a stable operation of the optical device based on the feedback signal. An apparatus, including an optical device having a cavity, a seed laser for generating a seed signal coupled to the optical device, a feedback generator coupled to the output of the optical device for generating a feedback signal, and means for adjusting a wavelength of the seed laser to maintain a stable operation of the optical device based on the feedback signal.
