tunable laser

in spectrochemical analysis
https://doi.org/10.1351/goldbook.T06529
A high intensity source with narrow spectral bandwidth, with and without @F02527@ and/or Raman shifting. Its use may enable the spectral apparatus to be omitted. Tunable lasers may be either continuous (CW) or pulsed in nature.
