摘 要：A non-magnetic temperature controlling system used in atomic magnetometer with flowing hot air has been designed and realized.To measure the temperature in the oven without any additional magnetic noise,a fiber Bragg grating was used as a non-magnetic temperature measuring sensor with a high relative accuracy.Analysis has showed the temperature fluctuation can be controlled less than O.1 ℃.
