US Army Research Laboratory Directed Energy Internship Program 2014

Abstract

This technical note is the final report for the 2014 Directed Energy Internship program at the US Army Research Laboratory. Six interns were mentored by 4 government employees. The projects included 1) a comparison of traditional erbium (Er):silica (SiO2) optical fiber to designs using Er: alumina (Al2O3) nanoparticles, 2) chirped seed amplification in a 1.6-kW ytterbium (Yb) fiber amplifier, 3) custom components for a 100-W Er amplifier, and 4) performance of coherent beam combining and power usage in fiber laser arrays with high fill-factor output. Three reports written by the interns are included as Appendices A through C. A report on the third project was published separately as ARL-TN-0672.
