Practical Broad-Band Tuning of Dye Lasers by Solvent Shifting [PDF]
We have operated a dye laser over a broad wavelength range (593.8-667.0nm) by shifting the dye emission profile with incremental changes of solvent composition. This was accomplished with the laser operating continuously, and only minor adjustment of the
