Laser frequency stabilization via bichromatic Doppler-free spectroscopy of an 87Rb D1 line

Minhua Zhao, Xunda Jiang, Ruihuan Fang +5 more

We demonstrate a bichromatic Doppler-free spectroscopy of an 87 R b D 1 line by using a dual-frequency, counterpropagating laser field with orthogonal linear polarizations. A reversed Doppler-free resonance dip is observed in the dual-frequency scheme, and a significant improvement of frequency discrimination curve is acquired due to the coherent population trapping (CPT) effect. The influence of the static magnetic field and laser intensity on the spectroscopy is studied in both single- and dual-frequency schemes. After locking the laser frequency to the 87 R b D 1 line in the dual-frequency stabilization scheme, the beat note fractional frequency stability is at the level of 7 × 10 − 12 at 1 s integration time. This technique can be used in various applications, such as CPT atomic clocks, laser spectroscopy, quantum optics, and laser-cooling experiments.

Absolute active frequency locking of a diode laser with optical feedback generated by Doppler-free collinear polarization spectroscopy

Zi Dong Liu, Daniel Bloch, M. Ducloy

Absolute stabilization of the emission frequency of a laser diode can be achieved in a nearly all-optical scheme involving a resonant optical feedback from an atomic signal. We propose here two novel schemes of collinear Doppler-free polarization spectroscopy and report on preliminary experimental demonstrations of diode frequency locking performed on the D2 line of Rb.
