Dilution chillers cooling heat atoms quantum states
2014/12/20
We consider the possibility of adding a stage to a dilution refrigerator to provide additional cooling by “filtering out” hot atoms. Three methods are considered: (1) effusion, where holes having diam...
25 kHz narrow spectral bandwidth of a wavelength tunable diode laser with a short waveguide-based external cavity
25 kHz narrow spectral bandwidth wavelength tunable diode laser short waveguide-based external cavity Optics
2012/4/19
We report on the spectral properties of a diode laser with a tunable external cavity in integrated optics. Even though the external cavity is short compared to other small-bandwidth external cavity la...
Spectrally narrow, long-term stable optical frequency reference based on a Eu$^{3+}$:Y$_{2}$SiO$_{5}$ crystal at cryogenic temperature
Spectrally narrow long-term stable optical frequency reference cryogenic temperature

Abstract: 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 determining the u...
