Multi frequency lasers are used for a variety of applications, including various types of spectroscopy, laser microscopy, hi-tech R&D, multiphoton excitation, light detection, non-contact inspection, photoacoustics and semiconductor processing.
Dual wavelength laser modules are available with a number of outputs, including Red-green and IR. Multi frequency laser systems emitting three or more wavelengths include multicolour RGB lasers that emit red, green and blue laser light simultaneously. RGB laser sources are frequently used for display and projection purposes.
