Estimating the term…
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.
