comment Resonant vs. Non-resonant Raman
I have never known for sure, but I suspect it is because the molecule is more likely to absorb and re-emit photons at those frequencies on the whole.

comment How to measure the size of a laser dot?
If you can pry the lens off the front of the camera, there is an easier way to get the size of the pixels on the sensor: illuminate the sensor directly with the beam, place a screen at a known distance from the sensor, and measure the distance (and therefore the angle) between the spots in the back-reflected diffraction pattern.

comment Do TN and IPS displays are subject to diffraction?
Don't overestimate others' familiarity with what seems easy to you. I learned what TN means long after I learned what a display is, and I have no idea what IPS is.

comment Collinearity of two infrared (10.6um) beams
While you're on the subject of safety, I'd suggest having the combined beam travelling horizontally, not upwards!

comment Transfer matrices - drift distances
I was thinking that would only work if $d$ was large compared with the difference in thickness due to the curvature of the lens; otherwise $d$ would not be constant in the distance from the optical axis, and so the transfer matrix would not work.

comment Why is optical orbital angular momentum (OAM) called “topological charge”?
Something else to point out is that the topological charge can be positive and negative and also adds up like electrical charge.

comment Anomalous Total Transmittance
You can't get out more energy than you put in, so I would guess something's wrong with your calibration.

Cu nanocrystals embedded in glass, though, wouldn't be able to tell much about the solid metal, right?
