| 20110044070 | LIGHT SOURCE DEVICE - A light source device includes a first semiconductor laser element that oscillates a first laser beam having a visible-region wavelength, a second semiconductor laser element that oscillates a second laser beam having a visible-region wavelength, and a light-scattering body that is irradiated with first laser beam and second laser beam to scatter first laser beam and second laser beam without changing the wavelengths. Because the wavelengths are not converted, first laser beam and second laser beam oscillated from first semiconductor laser element and second semiconductor laser element are emitted without generating energy losses of first laser beam and second laser beam. | 02-24-2011 |
