Compact, robust, and high-efficiency 1030nm laser transmitter for uplink beacon application for deep-space communication. Highly compact, and cost-effective low power (40100W) uplink laser beacons for near-Earth optical space communication links, e.g. as part of the NASA-SCaN roadmap. Alternately, using uplink laser beacons with higher powers, smaller aperture optical telescopes (~15-30cm) can enable high-bandwidth space optical communication links. The various design parameters and trade-offs are applicable to the design of other 1-m long-pulse lidar transmitters for NASA application (e.g. for atmospheric column sounding). Similarly, most principles carry over to the design of 1.5-m fiber laser/amplifier based lidar transmitters. Laser illuminator and high-rate fine-tracking for directed-energy (DE) applications. In fact, HEL-JTO has a very similar requirement for such laser sources to be used for tracking lidars. MDA applications for target identification and designation.
