Precision Cleaning/Sub-Micron Level Cleaning with Liquid/Supercritical Carbon Dioxide (CO2) Technology

Not Available Q-Peak, Inc. proposes to develop a broadly tunable, 10-W-average-power IR source suitable for use as a DIAL system transmitter and based on the combination of a Nd-doped pulsed pump laser and optical parametric oscillators (OPO). The laser source, a compact, diode-pumped, 5-10 kHz pulse-repetition-rate, Q-switched Nd:YLF laser, will pump a tandem OPO system consisting of an angle-tuned, 3-5 (magnetic moment)m KTA OPO, and a pump-tuned, 8-12 (magnetic moment)m CdSe OPO pumped by the KTA OPO idler. Diode-pumping and nonlinear conversion will substantially increase the efficiency of the proposed source whereas high pulse rates (5-10 kHz) will allow the possibility of reducing the data acquisition time. The Phase I effort will demonstrate a laboratory breadboard 2.5-5 W IR transmitter and develop a design for a higher-efficiency 10-W, 3-12 (magnetic moment)m tuning range IR-source.
