06529 IUPAC Gold Book - tunable laser 10.1351/goldbook.T06529 T06529 current 1 A high intensity source with narrow spectral bandwidth, with and without frequency doubling 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. frequency doubling https://goldbook.iupac.org/terms/view/F02527 PAC, 1988, 60, 1449.
