Adding wavelength versatility to conventional lasers using Stimulated Raman Scattering: could the dye die?

Visitor's room at 508

Solid-state Raman lasers are robust and efficient sources of laser output at otherwise "difficult to reach" wavelengths. Based on standard laser technology such as Nd-doped lasers or Ti:Sapphire lasers, they use stimulated Raman scattering (SRS) in nonlinear crystals to shift the output wavelength further into the infrared, with conversion efficiencies typically as high as 70%. When combined with frequency doubling, efficient conversion to the yellow-orange spectral regions, and the UV region can occur as well as the creation of devices with multi-wavelength and wavelength-selectable output.
