Abstract: A thulium-based high peak-power system is proposed for generating wavelengths near 1.89µm, suitable for conversion to blue wavelengths near 473nm via fourth-harmonic generation. The proposed 1.89µm system will be capable of producing 80mJ per pulse at PRFs greater than 200Hz,
Benefits: Laser system and technologies developed under this SBIR are directly applicable to Areté’s airborne ocean remote sensing imaging lidar products used for mine countermeasures (MCM), bathymetry, and sensing of other underwater objects. Areté’s commercial strategy is to leverage new developments spawned by this SBIR and apply them to products and systems in our existing marine imaging lidar portfolio. Because the overarching goal of a high-energy thulium laser developed under this SBIR is the generation of blue wavelengths, Areté’s vast experience in active ocean remotes sensing in the littoral zones is a spring-board for emerging opportunities in the deep ocean, where 2-SHG blue wavelengths are applicable. Recent programs in non-acoustic Anti-Submarine Warfare (ASW), like Claymore Mine (CM), indicate there may be resurgence in deep-ocean remote sensing opportunities. Areté is very familiar with non-acoustic ASW technology and applications. Areté has developed several blue-green lidar system platforms based on either our Streak Tube Imaging Lidar (STIL) or flying spot lidar technology. These platforms and systems are ideal candidates to host a blue laser for deep-water applications. Areté’s laser systems group develops custom, DPSSLs for airborne military applications. We provide custom solutions to internal and external customers (e.g. Boeing, NGC, Raytheon, Ball Aerospace, DRS). Areté has the capability to produce several lasers a month.
