    • A wavelength conversion device includes a laser light source that emits a fundamental wave; a wavelength conversion element that converts the fundamental wave into a second harmonic wave; and an optical system including a wavelength selective mirror that reflects the fundamental wave transmitted through the wavelength conversion element without being converted into the second harmonic wave, while transmitting therethrough the second harmonic wave generated by wavelength conversion, wherein the optical system makes the fundamental wave transmitted through the wavelength conversion element without being converted into the second harmonic wave enter the wavelength conversion element again to be subjected to wavelength conversion once or more than once, while being focused by the wavelength selective mirror, and the conversion efficiency in at least one of the second stage and stages subsequent to the second stage is higher than the conversion efficiency in the first stage, where the conversion efficiency in each stage is defined as: (a second harmonic wave generated in one stage)/(a square of the fundamental wave entered in the one stage).
    • 波长转换装置包括发射基波的激光光源; 将基波转换为二次谐波的波长转换元件; 以及包括波长选择镜的光学系统,其反射通过波长转换元件传播的基波而不转换成二次谐波,同时透过其中由波长转换产生的二次谐波,其中光学系统使得基波传播 通过波长转换元件而不被转换成二次谐波,再次被波长转换元件进行一次或多于一次的波长转换,同时被波长选择镜聚焦,并且至少一个 第二级和第二级之后的级别高于第一级的转换效率,其中每级的转换效率被定义为:(一级产生的二次谐波)/(输入的基波的平方) 在一个阶段)。
