摘要： A light source optical system used with an excitation light source configured to emit first color light includes a wavelength conversion unit configured to receive the first color light emitted by the excitation light source and emit second color light with a wavelength different from a wavelength of the first color light, There is a first optical system having a positive power and a second optical system having a positive power provided in this order in an optical path between the excitation light source and the wavelength conversion unit. When a ray parallel to an optical axis of the first optical system is incident on the first optical system, a ray emitted from the first optical system is incident on the second optical system while approaching the optical axis. The second optical system has under-corrected spherical aberration at a paraxial focal position of the second optical system.

摘要： A light source unit includes a first reflector having a reflection face; a second reflector having a reflection face; a plurality of light sources; and a light condensing optical system to condense light emitted from the plurality of light sources. Light beams emitted from the plurality of light sources are reflected at a first reflection position on the reflection face of the first reflector, and then reflected at a second reflection position on the reflection face of the second reflector. The second reflection position is close to an optical axis of the light condensing optical system compared to the first reflection position.

摘要： A light source unit includes a first reflector having a reflection face; a second reflector having a reflection face; a plurality of light sources; and a light condensing optical system disposed between the first reflector and the second reflector. Light beams emitted from the plurality of light sources are reflected at a first reflection position on the reflection face of the first reflector, and then reflected at a second reflection position on the reflection face of the second reflector. The second reflection position is close to an optical axis of the light condensing optical system compared to the first reflection position. The light condensing optical system is configured such that the light beam passes through the light condensing optical system at least two times when the light beams reflect between the first reflector and the second reflector.

摘要： A semiconductor laser includes: a p-type semiconductor substrate; a ridge having an active layer and cladding layers on the semiconductor substrate; a current blocking layer embedding side surfaces of the ridge; and an n-type contact layer on the ridge and the current blocking layer. The current blocking layer includes a first p-type layer, an n-type layer or a hole-trapping insulating semiconductor layer, a second p-type layer, a diffusion inhibiting layer, and a third p-type layer stacked, in order, from the semiconductor substrate. The n-type contact layer includes a p-type inverted region located in a portion of the n-type contact layer, in contact with the third p-type layer. Dopants in the third p-type layer diffuse into the p-type inverted region. The diffusion inhibiting layer is an undoped semiconductor material or a semi-insulating semiconductor material and inhibits dopants in the third p-type layer from being diffused into the active layer.
