Solvent: The solvent influences the peak wavelength of the dye.
Peak: Output maximum of tuning curve.
Effciency: Laser output at the maximum of tuning range, relative to pump laser output. Effciencies may change depending on configuration or pump power level.
Concentration: Amount of dye, in grams, for 1 liter stock solution. Higher concentrations cause a shift of tuning curves to the red, while lower concentrations may result in a blue shift.
