摘要：
A second harmonic generating method and apparatus is disclosed in which temperature of the nonlinear optical device is detected using a temperature sensor and the light output control is performed only when the temperature of the nonlinear optical device falls within a predetermined range through a comparison with a set temperature, so that the best peak can be selected. At no time is a different peak selected when the characteristics or operation conditions of the nonlinear optical device change.
