These would be single spatial mode lasers, which are diffraction-limited light sources capable of long-range propagation in a narrow beam. As such they would provide a key technology element for wireless power transmission systems that are based on photovoltaic receiver technologies. The high efficiency diode lasers that form a key part of the proposed light source are currently being developed with DARPA funding under the Super High Efficiency Diode Sources (SHEDS) program. Yb fiber lasers have received a great deal of development effort in the broader laser community and have produced both the highest efficiencies and the highest output powers seen to date from fiber lasers. The innovation provided by this project would be the development of a simple, robust and highly efficient means of coupling the specific SHEDS diode structures to Yb fiber lasers by using laser micromachining to form an integral mirror and Brewster input port on the Yb fiber.","startYear":2005,"startMonth":1,"endYear":2005,"endMonth":7,"statusDescription":"Completed","principalInvestigators":[{"contactId":167211,"canUserEdit":false,"firstName":"Glen","lastName":"Rines","fullName":"Glen A Rines","fullNameInverted":"Rines, Glen A","middleInitial":"A","primaryEmail":"grines@qpeak.com","publicEmail":true,"nacontact":false}],"programDirectors":[{"contactId":206378,"canUserEdit":false,"firstName":"Jason","lastName":"Kessler","fullName":"Jason L Kessler","fullNameInverted":"Kessler, Jason L","middleInitial":"L","primaryEmail":"jason.l.kessler@nasa.gov","publicEmail":true,"nacontact":false}],"programExecutives":[{"contactId":215154,"canUserEdit":false,"firstName":"Jennifer","lastName":"Gustetic","fullName":"Jennifer L Gustetic","fullNameInverted":"Gustetic, Jennifer L","middleInitial":"L","primaryEmail":"jennifer.l.gustetic@nasa.gov","publicEmail":true,"nacontact":false}],"programManagers":[{"contactId":62051,"canUserEdit":false,"firstName":"Carlos","lastName":"Torrez","fullName":"Carlos Torrez","fullNameInverted":"Torrez, Carlos","primaryEmail":"carlos.torrez@nasa.gov","publicEmail":true,"nacontact":false}],"website":"","libraryItems":[],"transitions":[],"responsibleMd":{"acronym":"STMD","canUserEdit":false,"city":"","external":false,"linkCount":0,"organizationId":4875,"organizationName":"Space Technology Mission Directorate","organizationType":"NASA_Mission_Directorate","naorganization":false,"organizationTypePretty":"NASA Mission Directorate"},"program":{"acronym":"SBIR/STTR","active":true,"description":"
The NASA SBIR and STTR programs fund the research, development, and demonstration of innovative technologies that fulfill NASA needs as described in the annual Solicitations and have significant potential for successful commercialization. If you are a small business concern (SBC) with 500 or fewer employees or a non-profit RI such as a university or a research laboratory with ties to an SBC, then NASA encourages you to learn more about the SBIR and STTR programs as a potential source of seed funding for the development of your innovations.
The SBIR and STTR programs have 3 phases:
The SBIR and STTR Phase I contracts last for 6 months with a maximum funding of $125,000, and Phase II contracts last for 24 months with a maximum funding of $750,000 - $1.5 million.
Opportunity for Continued Technology Development Post-Phase II:
The NASA SBIR/STTR Program currently has in place two initiatives for supporting its small business partners past the basic Phase I and Phase II elements of the program that emphasize opportunities for commercialization. Specifically, the NASA SBIR/STTR Program has the Phase II Enhancement (Phase II-E) and Phase II eXpanded (Phase II-X) contract options.
