Preliminary results on absolute frequency stabilization of Distributed Brag
g Reflector (DBR) diode lasers with emission wavelength at 852 nm are repor
ted, Saturated absorption Da lines of cesium atoms have been adopted as a f
requency reference and the nonlinear spectroscopy method of modulation tran
sfer has been used to lock the laser frequency against the resonance; The a
nalysis of the beat signal between two independent laser systems has showed
a relative frequency stability of 10(-11) for an integration time of 0.1 s
, and a frequency noise floor in the order of approximate to 10(-12) for an
integration time of 1 s seems attainable.
