Abstract

Q-Peak, Inc. proposes to develop a ~2-ns pulse, high-power, 10-kHz repetition rate, 1504-nm source based on the combination of an efficient, high-power, diode-pumped Nd:YLF master oscillator - power amplifier (MOPA) system and a double-pumped, KTA crystal-based optical parametric oscillator (OPO) for laser ranging applications. The overall goal of the program is to design and build a short-pulse, single-frequency source with average power of 100 W. In the Phase I effort we propose to design and build a short-pulse diode-pumped, Q-switched, Nd:YLF oscillator and a double-pass amplifier based on our multipass slab design generating >15 W of average power at a 10 kHz pulse rate. The Phase I effort will also include analysis and preliminary design of the entire two-channel MOPA and the OPO converter to the eyesafe wavelength range. A prototype system suitable for application as an airborne Lidar Transmitter will be built and delivered to MDA at the end of the Phase II program.
