Nanowire Laser (image) DOE/Lawrence Berkeley National Laboratory Share Print E-Mail Caption A nanowire, composed of cesium, lead and bromide (CsPbBr3), emits bright laser light after hit by a pulse from another laser source. The nanowire laser proved to be very stable, emitting laser light for over an hour. It also was demonstrated to be broadly tunable across green and blue wavelengths. The white line is a scale bar that measures 2 microns, or millionths of an inch.
