ALMDS (Airborne Laser Mine Detection System) has been developed utilizing a solid-state laser operating at 532 nm for naval mine detection. The laser system is integrated into a pod which mounts externally, centerline on a helicopter. This laser, along with other receiver opto-electronic systems enables detailed underwater bathymetry. CEO designed and manufactured the laser portion of this system. Arete Associates integrates the laser system into the complete LIDAR package which utilizes sophisticated streak tube detection technology. The laser sub-system is comprised of two separate parts: the LTU (Laser Transmitter Unit) and the LEU (Laser Electronics Unit). The LTU and LEU where put through MIL-standard testing for vibration, shock, temperature, storage and operation extremes as well as MIL-704E electrical power testing. The Nd:YAG MOPA laser operates at 350 Hz pulse repetition frequency at 50 Watts average power and is controlled at the system level in the helicopter. Power monitor circuits allow real time laser health monitoring, which enables input parameter adjustments for consistent laser behavior.
