Tunable laser

A typical laser diode. When mounted with external optics these lasers can be tuned mainly in the red and near infrared.

A tunable laser is a laser whose wavelength of operation can be altered in a controlled manner. While all laser gain media allow small shifts in output wavelength, only a few types of lasers allow continuous tuning over a significant wavelength range.
