tunable laser

…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…

Intense, tunable (adjustable-wavelength) light sources now span most of the visible, near-infrared, and near-ultraviolet portions of the spectrum. Lasers have been used for selected wavelength bands in the infrared to submillimetre range, and on the opposite end of the spectrum, for wavelengths as short as the…

…of spectroscopic studies, a high-intensity tunable narrow-band source is needed for conventional high-resolution spectroscopic studies. This type of source is provided by the dye laser, in which laser emissions arise from the decay of dye molecules that have been excited into a multitude of closely spaced rovibronic (rotational-vibrational-electronic) levels by…
