ABSTRACT:
A laser beam generator for making wavelength conversion automatically controls the length of an external resonator of a laser source to perform wavelength conversion at a high efficiency by pulling-in a servo using a resonator length error signal and a reflected light signal. A sample-and-hold circuit is used to detect the error signal from the detected light signal which is reflected from the external resonator.
