摘要： A wavelength conversion device performs adjustment so as to stabilize the energy conversion efficiency from a to- be-converted light into a converted light and maintain maximum efficiency. The wavelength conversion device includes: a laser light source (10) for generating a basic wave light; a non-linear optical crystal (16) for introducing the basic wave light and generating a converted light; and an optical path adjustment unit (30) for adjusting the propagation direction of the basic wave light and the position of the light flux of the basic wave light in order to input the basic wave light while satisfying the phase matching condition with the non-linear optical crystal. The optical path adjustment unit includes a first reflection mirror (12) and a second reflection mirror (14). The first reflection mirror has an adjustment unit driven by motors (M1, M2) and the second reflection mirror has an adjustment unit driven by motors (M3, M4). Moreover, the wavelength conversion device include: a translucent mirror (18) for extracting a part of an output light (17) by dividing it; and a photo-detector (22) for detecting the divided light. An electric signal (23) outputted from the photo-detector is inputted to adjustment value calculation means (26), where a necessary adjustment value of adjustment place of the optical path adjustment unit is calculated by the fuzzy reasoning and the calculation result is outputted to an optical path adjustment unit control device (28). The optical path adjustment unit control device adjusts the optical path according to an output signal (27) from the adjustment value calculation means.
