Power scaling of blue lasers with high peak-power and repetition rate for detection of underwater objects Navy SBIR FY2014.1 Sol No.: Navy SBIR FY2014.1 Topic No.: N141-008 Topic Title: Power scaling of blue lasers with high peak-power and repetition rate for detection of underwater objects Proposal No.: N141-008-0363 Firm: TIPD, L.L.C. 1430 N. 6th Ave. Tucson, Arizona 85705-6644 Contact: Lloyd LaComb Phone: (520) 626-1747 Abstract: TIPD LLC proposes to develop a diode-pumped, Q-switched narrow spectral-linewidth (< 0.1 nm) blue laser system capable of producing < 20 nanosecond pulses with pulse energy > 15 mJ at a repetition rate of 1 kHz for the detection of underwater objects. The blue laser is achieved by intracavity frequency doubling of a laser oscillator operating at a wavelength below 1 micron. The advantages of this laser system include high efficiency, high compactness, and power scalability. In this phase I program, we will focus on the demonstration of this new type of Q-switched laser oscillator operating below 1 micron and high efficiency second harmonic generation of the blue laser. Modeling and design of the whole laser system will be carried out as well. Benefits: The pulsed blue lasers can be used for silicon material processing, submarine imaging, oceanography LIDAR, underwater communications, data storage, undersea oil exploration, full color displays, and biomedical and medical applications. The high power fundamental near-infrared laser system can be used in industrial material processing, rock drilling, laser propulsion, and ultra-high intensity laser-matter interaction physics. Return
