Ultra-low Frequency Noise External Cavity Diode Laser Systems for Quantum Applications

Niklas Kolodzie, Ivan Mirgorodskiy, Christian Nölleke +1

We present two distinct ultra-low frequency noise lasers at 729 nm with a fast frequency noise of 30 Hz^2/Hz, corresponding to a Lorentzian linewidth of 0.1 kHz. The characteristic…
