Laser induced white emission
Laser-induced white emission is a broadband light in the visible spectral range. This phenomenon was reported for the first time by Jiwei Wang and Peter Tanner in 2010 for fully concentrated lanthanide oxides in vacuum, excited by a focused beam of infrared laser diode operating in continuous wave mode.
Laser diode
A laser diode is a semiconductor device similar to a light-emitting diode in which a diode pumped directly with electrical current can create lasing conditions at the diode's junction.
