Multi-Functional Laser Heat Source

To address the Navy need for a heat gun/soldering iron compatible with leaded and lead-free solders without risk of cross-contamination, and with all approved heat shrink and solder sleeves, for use in a Navy flightline maintenance environment, Physical Optics Corporation (POC) proposes to develop a new MultiFunctional Laser Heat Source (MFLaHS) based on a near-infrared laser diode, beam-shaping optics, laser driver electronics, and a rechargeable power source. The use of a laser ensures compatibility with all types of solder without risk of cross-contamination. The novel MFLaHS design is compact, lightweight, portable, stand-alone, and qualified for flight-line maintenance environments, with a long operating time. Its innovative beam-shaping optics provides optimal working distance with absolute safety for the surrounding materials and staff. These features directly address the PMA-261 and H-53 Helicopters requirements. In Phase I, POC will demonstrate the feasibility of MFLaHS by developing and demonstrating a functional prototype of technology readiness level (TRL)-4. In Phase II, POC plans to develop a TRL-7 prototype and conduct testing to demonstrate the operation of MFLaHS technology in a relevant environment.
