Winter 2020 - He prefaced this class by telling us it was the hardest physics lab offered for undergraduates. While I don't know how necessarily true this statement is, I personally found this class very, very, time consuming and difficult. What is nice is the collaborative atmosphere with fellow classmates because its so small (6 of us this quarter), so make friends quickly! It's hard because you're learning brand new skills every week which are the utter basics of optical design (AMO, physical chemistry, imaging science) , including polarizers, waveplates, lasers, optical cavities, etc. I personally don't have an immediate gift for experimental science and struggled quite a bit as I kept learning new things. The actual quantum part is the final experiment which is an experimental verification of Bell's Inequality (an optional Hong-Ou-Mandel). That being said, this class is so cool and more importantly, immediately useful. I thought optics from lower div was god awful boring until we started looking at the more advanced EM topics that you don't typically learn from 110 series. Plus, you get a stronger intuition for how QM works! Highly recommend but not for the faint of heart.

Spring 2024 - The instructor is nice. He is willing to help students and answer questions. He is a great person, and I would love to take his course again. The problem is the course content. I would rather die than doing any AMO experiments in my life again. I completely lost interest in AMO. The elective of optics is not offered, so all theory is new to me. I have to learn the theory and the experiments while writing all the reports and pre-labs. All of this takes all my time. All the experiments except the last two take so long, and when I left the labs, it was always mid-night. At least I can say confidently that there is no homeless people on campus in midnight because I was really physically on campus. The experiment s were hard to conduct, and sometimes the TA did the labs for us becuase we spent hours on it and couldn't succeed. For example, in the cavity lab, all the alignments were done by the TA because all our attempts failed miserably. After the labs, we spend so much time writnig reports and answer questions, but the TA grade harshly for some ridiculous reason. After constantly grinding and failing, the hopelessness made me lost hope of life and I started to weep lonely. Another thing to mention is that there is so much information in lecture, and every week after the lecture, my brain is cooked. I don't understand anything from lecture, and I have to self-study. Basically, I self-studied all the theory part, spending days and nights reading lecture notes myself. The instructor did his best, but we have so much material to cover in so little time. This should be a multi-quarter course. I now have a PTSD for lab course. It is completely different from my experience in an actual lab.
