Abstract: Illumination device for a motor vehicle headlight for producing a dipped beam distribution, which has a homogeneous light distribution in the region below the intersection HV up to at least ?3° along the vertical line V-V. The illumination device includes: (i) an illuminant for emitting light, (ii) a screen with a screen edge, wherein the screen includes a first and a second screen section, which are connected by a connecting section, and (iii) a projection optics system, which is designed to project the dipped beam distribution towards a main emission direction. The connecting section has a deflection surface, which extends along a plane with a spatial vector, which forms a first angle of 1° to 3°, preferably of 2°, to the first axis, and forms a second angle of 1° to 3°, preferably of 2°, to the main emission direction.

Abstract: In a system and method, the emitted beams of multiple diode bar array assemblies are combined to achieve an increase in the resulting power density in the combined output beam, while addressing the need for heat distribution in each of the individual assemblies. The present invention enables the combination of output planes of illumination, to form a single, merged beam of area Ag having intensity IM˜M*Istack and brightness BM˜M*Bstack, where Istack and Bstack refer respectively to the intensity and brightness of the output plane of illumination of a single stacked array, and where IM and BM refer respectively to the intensity and brightness of the combined output plane of illumination of M stacked arrays. In this manner, the present invention is useful in applications where there is a need for high-intensity, high-brightness light energy.

Abstract: Amplified spontaneous emission (ASE) ducts are disclosed for use with various gain media. An ASE duct may be configured and arranged to remove ASE from solid state or liquid gain media and transmit the ASE to an exterior optical medium. The refractive index of an ASE duct is selected as desired based on the refractive index of a gain medium and an exterior optical medium. An ASE duct may include first and second boundary surfaces joined at a vertex having an included angle that allows ASE (light) reflected off on one boundary surface to be incident on the another boundary surface at less than the critical angle and transmitted outside of the ASE duct. Laser systems using ASE ducts and methods of using and manufacturing ASE ducts are disclosed.
