8th Day of Christmas: Electro-Optic Modulator

This Advent during the 24 days leading up to Christmas I thought it would be fun to have a quick introduction of scientific apparatus, in particular tools used in atomic physics research. This is a way to say thanks to their hard work for our research, and a look at how many things are really needed to make a laboratory work!

Electro-Optic Modulator

The Electro-Optic Modulator (EOM) is similar to the Acousto-Optic Modulator (AOM) in that respect that both of them are manipulating the properties of a laser beam and that they look sort of similar from the outside, but similarities most end there. To recap, an AOM is using sound waves to change the direction a laser beam is going, shift its frequency, and split the power of the laser between multiple beams. The EOM on the other hand is modulating (or, changing periodically) the laser beam, and using a different setups it can achieve different interesting effects!
