Laser/active medium question.

  1. Aug 23, 2012 #1
    I have no doubt that someone, someone somewhere has tried this.
    but if you take a 10 WAT output from a argon beam and run it through a Rubie Active medium chamber I would expect that the light would be excited to a higher range.
    Am I in error?

    Why does the intensity of the beam matter?

    i presume you are referring to the 10 Wat's. one needs a starting point.

    Yes, you are in error. (Presuming by higher "range" you mean frequency).

    Why would you expect the light to be excited to a higher frequency with increased pump power?

    Perhaps the OP means to ask if the light would be amplified to a higher power via stimulated emission, as happens inside a laser.

    In this case, I would say no, as Ruby is used to amplify red light at 694 nm, whereas argon lasers produce blue or green wavelengths.

    I think you are right. I'm not as smart as you all. I like thinking of this stuff
    I prefer stellar physics.
    But..I wonder so much about so many things.

    So I am going to retry asking my question.

    I pump light in go a argon active medium chamber what i get out is 10 WATS of green beam. IF i put said 10 WATS in to a red active medium chamber. Will the output of the beam (assume only 1 watt due to the %90 loss) but the beam wave crests would be tighter, yes?
    or, would it have no effect at all but to recolor the light to red?
