<p>In a laser beam generator for making wavelength conversion with an automatic control of the length of an external resonator (3) or the resonator of the laser souce (6), for achieving a high efficiency wavelength conversion, the servo pulling-in is performed by use of the resonator length error signal and the reflected light signal. A sample-and-hold means is used to detect the error signal from the detected light signal which is reflected from the external resonator. <IMAGE></p>
