Mid-infrared lead-chlacogenide VECSELs emitting up to above RT at 4–6 um wavelength

摘要

We describe the first mid-infrared VECSELs (Vertical External Cavity Surface Emitting Laser) operating up to above room temperature. We employ a resonant design with a one wavelength optical thickness of the active layer (PbSe or PbTe). The structures are grown non-lattice matched on BaF
