Purcell-enhanced optical refrigeration
Peng Ju, Kunhong Shen, Stefan Püschel +3
Optical refrigeration of solids with anti-Stokes fluorescence has been widely explored as a vibration-free cryogenic cooling technology. A minimum temperature of 87 K has been demo…

Electrically-induced resonance shifts of whispering gallery resonators made of barium magnesium fluoride
Alexander Mrokon, Heike Kraft, Dongsung Shin +4
Barium magnesium fluoride (BMF) is a ferroelectric crystal with a transparency range far beyond the one of other optical materials. In particular, its low loss in the deep ultravio…
