Shortest-wavelength blue semiconductor laser reported

A research team from Brown University (Providence, RI) and Purdue University (West Lafayette, IN) have fabricated a semiconducting laser diode that operates at an emission wavelength of 463 nm--the shortest wavelength reported to date for this type of device. The separate-confinement heterostructure incorporated a ZnSe quantum well and ZnMgSSe barrier and cladding layers. The laser reportedly operated at room temperature under pulsed conditions, with average powers briefly reaching greater than
