Fluorescent material layer is formed on each side of a glass substrate of a fluorescent plate so as to interpose a reflective film therebetween. The first optical system optically guides, to a rod integrator, red and blue LED light, and green fluorescence that is generated by excitation occurring when blue laser light emitted from the solid-state light source unit is applied to the fluorescent material layer on one surface of the fluorescent plate, and that is emitted in the −X direction. The second optical system optically guides, to the rod integrator, red and blue LED light, and green fluorescence that is generated by excitation occurring when blue laser light emitted from the solid-state light source unit is applied to the fluorescent material layer on the other surface of the fluorescent plate, and that is emitted in the +X direction.

摘要： A multiple-lights-combining illumination device includes multiple light sources, multiple sub-rod integrators that respectively guide light from the multiple light sources, and a main rod integrator that guides light from the multiple sub-rod integrators. Each of the sub-rod integrators has reflection surfaces that are parallel to each other in a longitudinal direction, and has an entrance surface and an exit surface that are parallel or perpendicular to each other at ends thereof, the main rod integrator has reflection surfaces that are parallel to each other in a longitudinal direction, and has an entrance surface and an exit surface that are perpendicular to the reflection surfaces at ends thereof, and each reference optical axis that passes through an optical centroid portion of a light-emitting part of the light sources along a light emission direction is arranged so as to pass through substantially a center of the entrance surface of the respective sub-rod integrator. It is possible to use efficiently light while obtaining high intensity by combining light from multiple light sources, and furthermore possible to obtain a small and inexpensive device.

摘要： In nonlinear optical crystal 183D, each step of wavelength conversion can be performed using another fundamental wave that is output from light output unit 1612, without using the fundamental wave whose output level has been attenuated after going through wavelength conversion for several steps (wavelength conversion in nonlinear optical crystals 183A to 183C). Therefore, the wavelength conversion efficiency improves and the peak power of optical amplifiers 1611 and 1612 can be suppressed, which allows the wavelength of lights that are output from optical amplifiers 1611 and 1612 to be further narrowed.
