Blue fluoresence on a Lithium MOT
© 2020 Tigrane Cantat-Moltrecht / EPFL
We have observed blue light fluorescence on the lithium MOT in the microscope setup !
When sending light at 460 nm resonant with the 2P -> 4D transition of lithium on top of a MOT, we get nice fluorescence. Bonus: is goes through the cavity mirrors and can be collected directly !
