BOVINE PARAINFLUENZA 3 VIRUS AS A NOVEL VACCINE VECTOR

Not Available Q-Peak, Inc. proposes to develop a broadly tunable, l0-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 um KTA OPO, and a pump-tuned, 8-12 um CdSe QPO pumped by the KTA OPO idler. Diode-pumping and nonlinear conversion will substantially increase the efficiency of the proposed source whereas high pulse rates and fast wavelength switching will allow the possibility of reducing the data acquisition time. The Phase I effort will demonstrate a laboratory breadboard 2.5-5 W JR transmitter and develop a design for a higher-efficiency l0-W, 3-12 um tuning range IR-source. BENEFITS: Laser Source will enhance selectivity and sensitivity of chemical and biological agent identification in a low cost standoff detector. In the commercial sector the applications include wide-area pollution monitoring, process control and general scientific investigations.
