Tunable laser

No real laser is truly monochromatic; all lasers can emit light over some range of frequencies, known as the linewidth of the laser transition. In most lasers, this linewidth is quite narrow (for example, the 1,064 nm wavelength transition of a Nd:YAG laser has a linewidth of approximately 120 GHz, or 0.45 nm ). Tuning of the laser output across this range can be achieved by placing wavelength-selective optical elements (such a
