Multi-Band Eyesafe NIR Laser for HEL Applications

Accurate Automation Corporation (AAC) proposes to provide a source that can meet the requirements of this present solicitation using a technical approach based on recent breakthrough technology that has made it possible to design a scalable fiber optic laser that can operate in all of the low loss windows in the eyesafe NIR band. Based on a technique whereby the fiber core is doped by nanoparticles (NP) containing different rare earth ions, a single fiber can be made to behave as an independent amplifier at multiple signal wavelengths within these windows. Hence, a single wavelength band switchable and wavelength tunable source can meet the Phase I, II and III performance requirements. Moreover, the development of practical HEL sources in the NIR is converging on fiber optic lasers, so having a test source that can operate at all of the candidate eyesafe NIR fiber wavelengths is especially appropriate. High output power will be achieved by combining the output of several fiber amplifiers through a passive coherent combining technique.
