Hi FWHM on a velocity distribution provides me with a specific velocity. What does FWHM say about the velocity distribution, I mean, does FWHM give me the most probable velocity of the distribution or something like that? Thanks

Thank you for both answers, they helped a lot :-)

I have been looking into broadening mechanisms and I'm stuck at trying to provide a physical explanation for power broadening. I get how the math shows that at high intenseties the decay rate goes through the roof due to saturation, but how does this increased decay rate manifest in a spread of...

Wow, and what happened to the equation? It looked fine in pre-view. Sorry - don't know how to fix that :-/

Hi, I am reading about forces on a two-level atom. In my textbook (p. 30 in Laser cooling and trapping by Metcalf & Straten) it says that the matrix expression for the force F = e\frac{\partial}{\partial z}(<\vec{E}(\vec{r},t) \cdot \vec{r}>) has only off-diagonal entries. But how does...

Hi I have a problem where the flux of a particle beam is measured using a (nearly) perpendicular laser beam and a photomultiplier. I have a function looking like this: L(\nu) = \frac{\gamma/2}{(\nu - \nu_0 + kv)^2 +(\gamma^2/4)} I suppose this is a Lorentzian lineshape function...

Hi, I am trying to make a Magnesium source by curling up a tungsten wire with a block of Mg inside. Then by setting electricity to the tungsten wire, the Mg is heated and you get what out? Magnesium atoms? Magnesium ions? Thanks a lot /Carnot

Thank you for answering, I thought dressed states might be a specific term but from your reply, it seems to be more of a general term. I'm reading some unpublished lecture notes on quantum optics and my current issue is in regard to a lambda system (see attachment). I'm not sure what is ment...

Hi I have currently read about dressed states, but I don't get what it is. Does it have something to do with AC-Stark splitting? Hope someone can give me a nice explanation :-) Thanks

Hi I'm reading some articles about atomic clocks and they say that they probe the clock transition. What does it mean 'to probe a transition'?

That made it a bit clearer :-) Thanks a lot both of you

Hi What is a probability amplitude - I have read the article on wikipedia and I still don't get it. Hope someone out there can explain it to me.. Thanks

Hi, can someone please explain how a TOP-trap works? Thanks :)

Can someone please explain this concept for me? As I understand it, you have a, let's say, a three-level atom with two hyperfine states and an excited state. Then you apply a pump source (perhaps a laser) to transfer the atom from one of the hyperfine states (say |g1>) to the excited state...

This is my very first post in this forum, so please correct me, if I'm doing something wrong (if this is not the correct forum for this question or so), but can anyone please tell me what a structured reservoir is when we are working with decay and Markow approximation? As I understand it...
