Stabilizing an optical cavity containing a bulk diamond crystal at millikelvin temperatures in a cryogen-free dilution refrigerator
Tatsuki Hamamoto, Amit Bhunia, Hiroki Takahashi +1
We successfully stabilized a Fabry-Pérot optical cavity incorporating a bulk diamond crystal at millikelvin temperatures in a cryogen-free dilution refrigerator with the pulse-tube…
