Abstract

It has long been recognized that the detection and avoidance of Clear Air Turbulence can benefit both military and civilian airfleet operations in terms of passenger safety and comfort, as well as economic and mission performance. Among a variety of lidar systems under development, we are currently constructing a 2 μm Q-switched Tm,Ho:YLF laser transmitter/coherent receiver system specifically designed for CAT detection. Within this program, goal detection ranges are up to 20 km with real-time data update rates. This leads to a performance specification for the 2-μm laser system of 5 mJ at a repetition rate of 200 Hz with a 200 ns pulse duration. Towards this goal, we have recently demonstrated efficient operation of a Tm,Ho:YLF laser pumped by a 20-W fiber coupled CW laser diode array. We have obtained ~6 mJ of Q-switched pulse energy at repetition rates of 50 - 200 Hz and over 3 mJ at a 1 kHz repetition rate. In CW operation we have obtained over 4.5 W of power. In all cases the lasing mode was TEM00.
