Compact, High Average Power, Eyesafe Laser Development

Not Available This Small Business Innovation Research Phase I project will investigate the technical feasibility of fabricating an affordable blue laser array for projection displays. Our concept uses a new approach to fabricating lithium-niobate-based quasi-phasematching frequency converters to efficiently frequency-double low-power commercial diode lasers t produce blue light. A novel device architecture will be enabled by a new materials processing approach that will circumvent the main technical barrier to producing low-cost blue laser arrays: the need to rotate the polarization of diode laser light. In Phase I, we will demonstrate the scalability of this device concept to high-powers and multi-emitter arrays. In Phase II, we will fabricte prototype blue and green laser arrays. If successful, the proposed light sources will provide optimum power efficiency, high resolution, superior brightness, ideal spectral purity, and excellent dynamic range
