I don't know much about photonics, I understand even less, but I know one thing: I absolutely adore all these setups!
@gigabecquerel yeah I know little to nothing... but could look at those all day!
@concretedog But only with appropriate glasses ;-)
@gigabecquerel What is it - I mean I can tell it's some funky optics bench, but doing what?
@penguin42 I've been told it's an optical parametric amplifier, but I couldn't tell you anything about it
@gigabecquerel @penguin42 I can tell you from (long past) experience that calibrating such a beast is both tedious and incredibly satisfying. I spent hours adjusting tiny mirrors, always doubting if it will ever work again. And when it finally did, even though I (more or less) understood the maths and physics behind it, it still felt like a miracle.
