Robust laser frequency stabilization by serrodyne modulation
Robust laser frequency stabilization serrodyne modulation
2012/2/28
We report the relative frequency stabilization of a distributed feedback erbium-doped fiber laser on an optical cavity by serrodyne frequency shifting. A correction bandwidth of 2.3 MHz and a dynamic ...
Doppler-free two-photon resonances for atom detection and sum frequency stabilization
Doppler-free two-photon atom
2011/8/29
We investigate the excitation of the 5D5/2 level in Rb atoms using counterpropagating laser beams, which are nearly resonant to the one-photon 5S1/2 !5P3/2 and 5P3/2 ! 5D5/2 transitions, ensuring that...
Frequency-stabilization to 6x10^-16 via spectral-hole burning
spectral-hole Frequency-stabilization to 6x10^-16
2011/8/29
We demonstrate two-stage laser stabilization based on a combination of Fabry-P磂rot and spectral-hole burning techniques. The laser is first pre-stabilized by
the Fabry-P磂rot cavity to a fractional-fr...
