Optical properties of PbIn6Te10 in the long-wave IR

Optical properties of nonlinear PbIn6Te10 (PIT) crystal were studied for the first time within 30-1200 μm (0.2-15 THz) by FTIR and THz-TDS. It was found that PIT possesses the most attractive transparency features for efficient generation of long-wave mid-IR emission including 20-60 μm (5-15 THz) re...

Description
Summary:Optical properties of nonlinear PbIn6Te10 (PIT) crystal were studied for the first time within 30-1200 μm (0.2-15 THz) by FTIR and THz-TDS. It was found that PIT possesses the most attractive transparency features for efficient generation of long-wave mid-IR emission including 20-60 μm (5-15 THz) region by optical rectification. This crystal is also found useful for phase matched DFG generation into the long-wave THz region. In particular, by model study phase matched down-conversion of CO and CO2 laser lines into 130-1200 μm (0.3-2.3 THz) range is shown possible by ooe and eoe type of three wave interaction. Noncritical 90° phase matching for eoe type of interactions can be realized by selecting samples with specified composition. © 2016 Astro Ltd.
