METHOD FOR MODULATING AN ATOMIC CLOCK SIGNAL WITH COHERENT POPULATION TRAPPING AND CORRESPONDING ATOMIC CLOCK
摘要
<p>The invention concerns a method for modulating an atomic clock signal and a corresponding atomic clock. The laser beams (L1, L2) are pulse-modulated in amplitude to illuminate (A) an interactive medium. A detection (B) of the current pulse (Sr) and of the pulses (Sr-1 to Sr-p) preceding said current impulsion is performed. Said pulses are superimposed (C) by linear combination to generate a compensated atomic clock signal (SHC) whereof the spectral width is minimized. The invention is applicable to atomic clocks with pulsed interrogation whereof the interactive medium consists of thermal or laser-cooled atoms.</p>
