| 20120128015 | Optical Pumping of Solid-State Laser Material Using Addressable Laser Array - An array of Surface Emitting Laser (SEL) elements can be used to efficiently pump a disk or rod of solid-state laser glass or crystal, or harmonic-generating crystal. Placing the laser array chip against or near the surface of this solid-state material provides very high and uniform optical power density without the need for lenses or fiber-optics to conduct the light from typical edge-emitting lasers, usually formed in a stack of bars. The lasers can operate in multi-mode output for highest output powers. Photolithography allows for an infinite variety of connection patterns of sub-groups of lasers within the array, allowing for spatial contouring of the optical pumping power across the face of the solid-state material. The solid-state material may be pumped either within (intra-cavity) or externally (extra-cavity) to the SEL laser array. | 05-24-2012 |
| 20110279903 | OPTICAL BEAM BUNDLE COMBINER FOR MULTIPLE LASER ARRAYS - One or more combiner elements are disclosed for optically combining multiple laser beam bundles, either extra-cavity or intra-cavity to the laser generating array chips, to form higher density bundles of parallel laser beams. The combiner elements can be shared between two or more array chips and include a form of a pellicle combiner, a polarizing beam splitter cube combiner, or some combination of the two devices. | 11-17-2011 |
| 20110176567 | MULTIBEAM ARRAYS OF OPTOELECTRONIC DEVICES FOR HIGH FREQUENCY OPERATION - A VCSEL array device formed of a monolithic array of raised VCSELs on an electrical contact and raised inactive regions connected to the electrical contact. The VCSELs can be spaced symmetrically or asymmetrically, in a manner to improve power or speed, or in phase and in parallel. The VCSELs include an active region positioned between two mirrors generating a pulsed light operating at a frequency of at least 1 GHz. The VCSELs having an output power of at least 120 mW. The raised VCSELs and raised inactive regions are positioned between the electrical contact and an electrical waveguide. | 07-21-2011 |
| 20110148328 | SYSTEM AND METHOD FOR COMBINING LASER ARRAYS FOR DIGITAL OUTPUTS - Embodiments comprise a device that can efficiently produce a highly resolved intensity profile that can be easily switched to various specific configurations with binary word strings defining output intensities that after summation will be combined to form a single colors intensity depth. Arraying these devices allows an image line of single color pixels to be efficiently produced without gross scintillation effects. The non-coherent output is desirable in this application as it reduces scintillation effects on the screen or final image. | 06-23-2011 |
