Abstract
The invention is directed to an apparatus and method for oscillator start-up control, and more particularly to an apparatus and method for overdriving a laser to obtain mode-lock operation. The oscillator with start-up control has a lasing medium mounted on a base. A laser pumping source is mounted on the base for inducing a laser beam from the lasing medium. A mode-lock detection device is mounted about the base. An overdrive circuit is coupled with the mode-lock detection and signal processing device for determining mode-lock status of the oscillator. The overdrive circuit overdrives the pump source when the oscillator is not in mode-lock status.
