Discussion Overview

The discussion revolves around the effects of using different active mediums on laser output, specifically examining whether light from an argon laser can be modified when passed through a ruby active medium chamber. Participants explore concepts related to light frequency, intensity, and amplification through stimulated emission.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant suggests that running a 10 W output from an argon beam through a ruby active medium could excite the light to a higher range, questioning if this assumption is erroneous.
  • Another participant questions the relevance of beam intensity in this context.
  • A clarification is made regarding the starting point of the 10 W output, implying it is necessary for further discussion.
  • One participant asserts that the expectation of higher frequency excitation is incorrect, asking why increased pump power would lead to such an expectation.
  • Another participant proposes that the original question might concern amplification through stimulated emission, stating that ruby amplifies red light at 694 nm, while argon lasers produce blue or green wavelengths, suggesting no amplification to a higher power would occur.
  • A later reply expresses uncertainty and seeks to rephrase the question, asking whether pumping light into a ruby active medium would result in tighter wave crests or merely recolor the light to red, while acknowledging potential losses in output power.

Areas of Agreement / Disagreement

Participants express differing views on the effects of using different active mediums, with no consensus reached regarding the outcomes of passing argon laser light through a ruby medium. The discussion remains unresolved with multiple competing perspectives.

Contextual Notes

There are assumptions regarding the nature of light amplification and frequency changes that are not fully explored. The discussion also involves uncertainties about the effects of losses in output power when transitioning between mediums.

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?

Claude.
 
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 into 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?
