VCSEL technology offers an excellent choice for the development of such laser pumps. Princeton Optronics has developed the technology of high power VCSEL arrays delivering hundreds of watts of power from small chips with >55% efficiency at 976nm. We would use improvements of those techniques as well as some new approaches to 808nm VCSELs to develop very high efficiency high power pumps. We propose an approach in which we would use improved quantum wells and other improvements on how the quantum wells are arranged in the cavity to dramatically improve the efficiencies of the VCSELs at 808nm. In phase I, we would demonstrate the feasibility of the approach and in phase II we would deliver >100W arrays with very high efficiencies as required in the solicitation. Benefits: There is a very large market for diode pumps for solid state lasers. The market is largely for 808nm pumps and is estimated to be over $100M. We would be able to capture at least 15% of this market in a few years with the superior performance VCSEL product that we would develop in this SBIR and its lower cost. In terms of the military market, there is a multi-million dollar DPSS market which is now being supported by edge emitter pump companies. Once we develop the VCSEL based pumps, a good part of the market would change to the VCSELs. Princeton Optronics has a strong manufacturing, marketing and sales capability to capture a significant part of the market, once the product is developed. We expect a sales level at least in the range of $5-10M in two to three years after development of the products in this SBIR. Return
