Quick Summary

A tunable laser is a type of laser that can have its output wavelength adjusted. This tunability is crucial for various scientific applications, particularly in spectroscopy, where precise control over the light's wavelength is needed to study molecular energy levels.1

Unlike standard lasers that emit a narrow range of wavelengths, tunable lasers, such as dye lasers, can be adjusted to emit light across a broader spectrum by changing the dye or pump source. This capability allows researchers to probe specific transitions in molecules that would otherwise be inaccessible with fixed-wavelength lasers. The ability to tune the laser's output is a key characteristic that distinguishes it from other laser types.12

Lasers for RIS
…components of RIS methods are tunable lasers, which can be of either the pulsed or the continuous-wave variety. Pulsed lasers are more frequently used since they can add time resolution to a measurement system. In addition, pulsed lasers produce high peak power, permitting the efficient use of nonlinear optics to…
