1Advances in NLO crystals for infrared parametric sources Peter G. Schunemann BAE Systems, Inc. Electronic & Information Solutions (E&IS) MER15-1813, P.O. Box 868, Nashua, NH 03061 ISLNOM-3: New Mid-IR NLO Crystals 2/9/2007 2 Improved NLO crystals are critical for advancing mid-IR laser development • Higher efficiency and output power in the 2-8mm spectral range • Mid-IR crystals compatible with 1-Micron (Nd and Yb) pump lasers • Better long-wavelength materials for CO2 doubling and 8-12mm generation • Desirable properties: – High nonlinear coefficient – Low absorption loss – High laser damage threshold – Low thermal lensing – Non-critical phase matching (NCPM) • • • idler signal pump C-axis Birefringence Crystals QPM Semiconductors
