Abstract

Summary from only given. We report our first result of achieving the coherent mid-IR and far-IR radiations with extremely-wide tunability and narrow linewidth in a GaSe crystal. As shown below, we have extended the output wavelengths to the far-IR. In our DFG experiment, the two mixing beams used for the DFG consists of the idler beam of an OPO pumped by a frequency-tripled Nd:YAG laser and the residual Nd:YAG fundamental beam.
