Paper Abstract

In this paper, the performance of a compact, eyesafe, all-solid-state, mid-wave IR (MWIR) transceiver for data communication through low visibility conditions is discussed. The transceiver was developed for Multiple Integrated Laser Engagement System (MILES) application. The MWIR wavelengths are derived using a passively q-switched Nd:YAG laser pumped periodically poled lithium niobate based optical parametric oscillator. MILES weapon code transmission for small and heavy weapon platforms have been demonstrated through dense theatrical fog. With 2 μJ/pulse at ~4 mm and a room temperature IR detector, greater than 5 km range has been successfully demonstrated. A bit map image transmission at MWIR wavelengths was also accomplished using this device. Test images consisting of 50x40 pixels and 100x80 pixels were successfully transmitted through free space.
