Various CW lasers can be used for specific applications, typcially in semiconductor research. Laser beams can be
directed through a port in the spectrometer directly onto the sample. Continuous Wave (CW) single wavelength laser sources include:
- Argon Ion (Ar+ ion)
- Helium Cadmium lasers (HeCd)
- Neodymium Yttrium Garnet (Nd:YAG)
Pulser boxes are available for some CW laser sources.
