Sorry for the delay in responding, been out of town.
This is in response to sophiecentaur's post concerning my odd use of quotes in regards to photons and physical interactions. But before attempting to offer an explaining, I’d like to say that while I’ve always been interested in physics, it...
I’ve got to apologize again for all of my questions, I’m a teachers worst nightmare because I’m never happy with the answer “just because”. Okay for that matter I drove my parents crazy as well.
There are times a red flag starts waving in the back of my head giving me a feeling that something...
The big problem with muscle cramps in ones head is that you can’t massage them away.
Depending on the type of gain medium and it’s atomic structure, is it possible to have more then one electron sitting at excited energy levels at the same time, and if so, can they become stimulated and emit...
Okay, um so do you ever feel like your brain has a Charlie-Horse?
Sorry for all of the questions and I really appreciate the help as I try and let this all sink in.
Within the resonance cavity you have photons of different wavelengths traveling in different directions, but a photon is a photon...
When I try picturing an active resonance cavity, I end up with images of total chaos as photons are zipping around in every direction. When one does find a desirable photon that will eventually pass through the less reflective end, must it have been emitted exactly perpendicular to the mirrors?
Marisa - thanks for the response.
I can understand the thinking that unwanted photons reflected from the chamber walls could be detrimental, but wouldn't that be offset by desirable photons being kept in play from mirrored sides?
It seems like loosing desirable photons through the side walls...
Thanks for the info.
When referring to an upper laser level, is that also what's called a metastable state or level?
So in 3+ level lasers, if spontaneous emissions can aid in the population inversion, would it not be beneficial to mirror the sides of the resonance chamber as well as the ends...
Hello, new here with lots of questions and minimal knowledge of physics.
If I understand this correctly, when spontaneous emissions take place within a LASERs resonance chamber, they are not of the desired frequency nor are they paired with other coherent photons. So are they still desirable in...
