Spectrally narrow, long-term stable optical frequency reference based on a Eu $^{3 +}$ :Y $_{2}$ SiO $_{5}$ crystal at cryogenic temperature

Qun-Feng Chen, Andrei Troshyn, Ingo Ernsting +4

Using an ultrastable continuous-wave laser at 580 nm we performed spectral hole burning of Eu $^{3 +}$ :Y $_{2}$ SiO $_{5}$ at very high spectral resolution. Essential parameters determi…

Thermal noise of whispering gallery resonators

Akobuije Chijioke, Qun-Feng Chen, Alexander Yu. Nevsky +1

By direct application of the fluctuation-dissipation theorem, we numerically calculate the fundamental dimensional fluctuations of crystalline CaF2 whispering gallery resonators in…
