摘要： An apparatus for manufacturing a light source and a method therefor are provided that enables a high efficient light source to be manufactured even when an optical element whose characteristic significantly varies is used. After maintaining temperatures of a laser device and a wavelength conversion element at a temperature where an output of light emitted from each of the device and the element is equal to or greater than a predetermined rate of the maximum output, the laser device and the wavelength conversion element whose temperatures have been maintained are joined together so that the output of the light emitted from the wavelength conversion element is equal to or greater than a predetermined value.

摘要： Because a reflector that reflects a fundamental wave generated from a solid-state laser element and forms an optical resonator is disposed on an exit surface of a wavelength conversion element, the fundamental wave cannot be resonated and amplified in a stage before the wavelength conversion element is joined to the solid-state laser element. As a result, a problem is created in that the solid-state laser element emits low level light output, so that a relative position of the semiconductor laser and the solid-state laser element cannot properly be adjusted. In order to overcome the above problem, even in the stage before joining the wavelength conversion element to the solid-state laser element, the invention enables the semiconductor laser and the solid-state laser element to be joined by properly adjusting the relative position of the laser and the laser element. A second reflector is provided that is located opposite a first reflector of the solid-state laser element and that partially transmits through the fundamental wave emitted from the solid-state laser element and reflects the rest of the wave. The semiconductor laser and the solid-state laser element are joined together at a relative position such that the output of light having passed through the second reflector reaches or exceeds a predetermined value.

摘要翻译： 因为反射从固态激光元件产生的基波形成光谐振器的反射器设置在波长转换元件的出射表面上，所以在波长转换元件为波长转换元件之前的阶段中，基波不能被谐振和放大 连接到固态激光元件。 结果，产生固体激光元件发射低电平光输出的问题，使得半导体激光器和固体激光元件的相对位置不能适当地调节。 为了克服上述问题，即使在将波长转换元件接合到固体激光元件之前的阶段中，通过适当地调整半导体激光器和固态激光元件的相对位置，能够使半导体激光器和固体激光元件接合 激光和激光元件。 提供了与固态激光元件的第一反射器相对的第二反射器，并且部分透射通过从固态激光元件发射的基波并反射波的其余部分。 半导体激光器和固体激光元件在相对位置处接合在一起，使得通过第二反射器的光的输出达到或超过预定值。
