摘要： An object of the present invention is to provide a laser source including a submount, an electrode portion formed on the submount, and a semiconductor laser fixed to the electrode portion by means of an adhesive portion, capable of improving the position accuracy of a laser beam emission portion of the semiconductor laser in the height direction. The electrode portion including an electrode for an active region, an electrode for a phase adjustment region, and an electrode for a DBR region is formed on the submount. A plurality of stopper portions also are formed on the submount. The semiconductor laser is fixed to the electrode portion (the electrode for an active region, electrode for a phase adjustment region, and electrode for a DBR region) by means of solder as an adhesive while being in contact with the stopper portions.

摘要： A light source device can attain a stable output of a harmonic even when there occurs a change in the ambient temperature or fluctuation in the output power. The light source device is provided with a semiconductor laser source (4), an optical waveguide-type QPM-SHG device (5) for generating a second harmonic from light emitted from the semiconductor laser source (4), a wavelength control means (7) for controlling a wavelength of light emitted from the semiconductor laser source (4), a means for slightly fluctuating wavelength (8) for changing a wavelength of light emitted from the semiconductor laser source (4) and a means for detecting a change in output light power of the optical waveguide-type QPM-SHG device (5) that occurs when a wavelength of light emitted from the semiconductor laser source (4) is changed. In this case, a wavelength of light emitted from the semiconductor laser source (4) is controlled to an optimum wavelength of the optical waveguide-type QPM-SHG device (5) based on a change in output light power of the optical waveguide-type QPM-SHG device (5) that occurs when a wavelength of light emitted from the semiconductor laser source (4) is changed.
