comment Momentum change of a photon upon diffraction at a grating
That would be explained in the answer that I originally thought was a duplicate of this one. The wave vector is modified when the light is diffracted by the grating.

comment does photon travels in a helical path in an optical vortex?
Although, the ring is an eigenfunction of the Fourier transform, but a small arc of it is not, so the small arc will not remain invariant during propagation...

comment difference between plasmonic wave plates and usual wave plates
I'm not sure what you're asking here. Plasmonic waveplates are different from birefringent glass ones, because they work according to a different mechanism. What is it you want to know about them?

comment Is there any review paper on spatial light modulator?
I don't know of a review paper, but I have a technical report from quite a while back, about characterizing a micro mirror array, which is a specific type of spatial light modulator.

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.
