The single-frequency laser model TIS/Dye-SF-777 is the improved Version of TIS/DYE-SF-07 and is a combination of solid state Ti:Sapphire and dye
laser in a single unit.
Switching of TIS/DYE-SF-777 from the Ti:Sapphire to the Dye laser operation and vice versa is performed by exchange of some cavity elements in which the majority of alignment controls, part of optical elements, and the electronic control unit remain the same for both versions.
