I'm doing an experiment with SPPs (Surface Plasmon Polaritons) on a metallic hydride, coupling the beam to the surface with a BK7 prism. I'm needing either a tunable laser that can include the range from 635nm to 609nm, or alternately, a 609.5nm source.
Are either available for less money than the frequency of the beam in gHz?
I suppose it doesn't need to be in the 6xx nm bands, but any two sources that I can get a 20.8tHz difference between them should be worth a shot.
Thanks!
