Abstract
A laser system includes a laser diode with a low dimensional nanostructure, such as quantum dots or quantum wires, for emitting light over a wide range of wavelengths. An external cavity is used to generate laser light at a wavelength selected by a wavelength-selective element. The system provides a compact and efficient laser tunable over a wide range of wavelengths.
