Temperature-insensitive laser frequency stabilization with magnetic tuning.
We have implemented a tunable laser frequency lock with a wide recapture range and low sensitivity to temperature fluctuation, based on electronically power-normalized Doppler-broadened absorption spectra. The method requires no frequency modulation. A distributed-feedback diode laser locked to this system exhibits submegahertz stability over many hours. It has been used to magneto-optically trap rubidium atoms for a full day.
