Demonstration of UV-A stimulated emission from optical pumping with a nano-porous cladding layer

We report a room-temperature ultraviolet-A (UV-A) stimulated emission from a multiple-quantum-well laser diode featuring a nano-porous bottom cladding layer on the GaN substrate. For a 1500×15 μ m ridge-type edge-emitting laser, we achieved a 372.8 nm emission under optical pumping, with a full-widt...
