Oh, I was looking the answer in the wrong place: I will have to remove the dust from my Sakurai. Thanks a lot!

Hi, I have been reading the Milonni and Eberly book "Laser": in one of the chapters they discuss the Oscillator Model. The treatment is quite straightforward, the Hamiltonian of the process is H=H0+HI where the first term is the "undisturbed" hamiltonian, and the second one is the interaction...

Hi, I have a problem that I'm trying to solve and I'm not sure at all how can I proceed. If we have a metal rectangle (or maybe a rectangle-shaped hole in a piece metal), and we stretch this body a small distance, what is the shape of the top and bottom lines of the body? Can we say it is a...

Well, z is the third component of the position. The author explicitly puts it there, but I don't find why. And actually, I think that the formulas for the FT of derivatives will take me to the answer, but I'm still working on it. I really appreciate the hint (I was very, very stuck). Let's...

Hi guys, I have been trying to solve the Helmholtz equation with no luck at all; I'm following the procedure found in "Engineering Optics with MATLAB" by Poon and Kim, it goes something like this: Homework Statement Homework Equations Let's start with Helmholtz eq. for the complex amplitude ##...

Hi, I'm a physicist intern that has some problems with Optics simulations; I'm very interested in doing some Beam Propagation Method (BPM) simulation, but the information online is not that good for begginers in the area. Can anyone advise me on books, journals or such that might help me learn...

Hi, I'm (almost) a Bachelor in Physics so I wanted to be part of this great commmunity on the Internet; perhaps I could learn something in the process, or maybe I can contribute something to anyone in doubt!
