【Abstract】 A new type Cs atomic resonance filter (ARF) datected by field ionization was reported. Theoretical analysis gives that the atomic inherent time response is of 1 us,quantum efficiency is of 99% and line width is of 60 MHz. Preliminary measurement gives that the ARF’s time response are of 130 ns, 120 ns and 120 ns; and critical signal laser energy is of 10 nJ for each pulse.更多还原
