Tunable Solid-State Mid-IR Laser Engineering

Abstract

This report describes in-house efforts to develop advanced tunable mid-IR laser materials and nonlinear frequency conversion techniques useful for IRCM and laser radar sources. We developed a new class of laser materials, Cr2+doped II-VI materials, with broadband tunability in the 2-3 micron region with room temperature operation and 4.2-W output. We fabricated periodically poled ferroelectric materials and demonstrated broadband tuning and narrowband seeding. We demonstrated pulse energies of 60mJ from a stack of periodically poled lithium niobate wafers. Other patterned nonlinear materials such as orientation patterned GaAs were characterized and show great promise for tuning throughout the 1.5-14 micron region.
