摘要： A light source device includes a light source unit emitting light of a first wavelength and a wavelength converting element converting light of the first wavelength into light of a second wavelength. An external mirror transmits light of the second wavelength toward an emission destination and reflects light of the first wavelength to resonate between the light source unit and the external mirror. A wavelength separating section transmits light converted from the first wavelength to the second wavelength while traveling from the external mirror to the light source unit and reflects light of the first wavelength in order to separate the different wavelength light. A turnback section reflects light of the second wavelength separated by the wavelength separating section toward the emission destination. In addition, the wavelength separating section reflects light of the first wavelength from the light source unit to travel toward the wavelength converting element.

摘要： The controller 170 controls the output power of the semiconductor laser device 100a depending on the temperature of the semiconductor laser device 100a acquired by the temperature sensor 130. The controller 170 references the correspondence table 510 when the sensor temperature Ts is obtained, obtains the output power PWs corresponding to the sensor temperature Ts, and controls the power supply driving circuit 150a so that the output power per unit time of the semiconductor laser device 100a will be the output power PWs. Thus increase in temperature of the semiconductor laser device is able to be prevented through reducing the output power by controlling the amount of power supplied to the semiconductor laser device. As a result, it is possible to prevent reductions in the service life of the semiconductor laser device, even when there is a failure in a cooling device that cools the semiconductor laser device, and even when the device is used in a high temperature environment not envisioned at the time of manufacturing.
