SBIR-STTR Award

This proposal addresses the problem of PCSS/laser trigger integration using a single monolithic laser diode array, thus simplifying the entire optical delivery network necessary for efficient operation of PCSSs. Phase 1 effort will focus on (1) overall feasibility study of integrating PCSS with a miniature laser diode array, (2) tradeoff analysis between several options, which will result in choosing the most suitable PCSS and laser diode array and (3) the detailed design of the PCSS/laser diode array integrated architecture.

This proposal addresses the problem of PCSS/laser trigger integration using a single monolithic laser diode array, thus simplifying the entire optical delivery network necessary for efficient operation of PCSSs. The proposal constitutes a logical continuation of Phase I effort where the main focus was on the detailed design of the PCSS/laser diode array (LDA) integrated architecture. In Phase II we will fabricate a prototype high-gain, high-power integrated PCSS/laser diode array module paving a way to an ultimate PCSS/LDA package capable of holding off of at least 40kV and having multiple filaments (channels) with total current exceeding many 1 kA.
