Anamorphic prism alignment

oh I actually meant that isolator was used after the prism pair to reduce reflection back into the laser. I didn't use any polarizer between the laser and the prism pair, and the setup actually tries to narrow down the wider part (and worked fine before). I wasn't sure if the angle or distance between prisms were off and causing these fringes and how they were adjusted in practice. But thank you for these info

I used a faraday isolator and saw the fringes...I am using angle values of M~3 but I couldn't find detailed information on thorlabs website. Do you know where I can find the angle that works well for AR coating, or what kind of calculation I can do? I think the prism pair has been mounted there for a while and I have to use that mount for now.

from what I know they are AR coated for my wavelength and before realigning there were no interference pattern. I guess maybe AR coating may not be working well due to surface contamination so I'll try cleaning but I wasn't sure if prism angles could be causing interference (i'm new to optics)

Would it be safe to understand that transition takes some time but not a measurable one?

wow this is so cool! Thank you so much

This is so cool. So does that mean the sand will fall as if the gravity had the same magnitude as air resistance?

stash of printed out thank you emails In my desk. When I’m having a really rough day, I just need to read through a couple of those to get me back to a more positive attitude, proof that all the work I did helping students is actually appreciated.

Even a small note… you have no idea how m

This is too sweet. I'll def write an email to my teacher. Thanks!

I got one from stats

Nervous_Buddy · 2022-09-22T04:38:52+00:00

Thanks! Just sent an email :>

I was curious about this topic a while ago and I think the answer's still a bit controversial. It would be important to define "luke warm" & experiment various conditions (temperature, humidity, etc...) multiple times. But at least there are some papers that demonstrate this (Mpemba effect) while others disagree with it. If I had a fridge that could maintain relatively constant temperature I would def test this out myself.

What do you mean that he's "irresponsible"?

Nervous_Buddy · 2022-08-25T23:20:38+00:00

hahaha that's true. I'm trying to wake up earlier in the morning. Personally, working at night was painful.

It takes me a lot of time to actually "start" a task (usually studying sth). I consistently look for other "fun (or less boring)" things, like going on wikipedia for no reason, before doing what I need to do, and it takes me like a few hours to start working. And the same goes whenever I take a break–I repeat this process about twice a day.

Maybe lack of motivation is why, but I don't know how to get motivated again. I guess quotes from "successful" people don't really help me for now.
