英文摘要：

So far, the only Ca magneto-optic atomic filters reported are based on a heated Ca cell, and the transmission spectrum obtained is double-peaked with 3 GHz effective passband limited by Doppler broadening. A magneto-optic atomic filter with single-peaked transmission spectrum of sub-Doppler bandwidth based on the thermal Ca atomic beam is firstly experimentally demonstrated. The fast Ca dipole transition （1S0-1P1） at 422.7 nm, which matches a strong solar Fraunhofer line, was utilized. A folded nine- beam traveling wave configuration is employed, and the maximum transmission efficiency is measured to be 7.3 %. A sub-Doppler transmission bandwidth of 590 MHz, much narrower than the 2.2 GHz Doppler width in the heated atomic cell, is obtained for the first time.
