摘　　要：We present our experiment on magnetic field induced spectroscopy of the ^(1)S0–^(3)P0 transition of ^(88)Sr atoms with a 10 Hz linewidth laser.The ^(88)Sr atoms are cooled by two stage laser cooling.After the second stage narrow line laser cooling,the temperature of the atoms is reduced to~3μK.The atoms are then loaded into an 813 nm one-dimensional optical lattice.A homemade 698 nm laser with 10 Hz linewidth and maximum intensity of more than 100 W/cm2 is used to probe the ^(88)Sr atoms in the lattice.By means of a magnetic field of~1 mT and a probe laser with 50 ms pulse and~6 W/cm^(2) intensity,the Doppler free ^(88)Sr ^(1)S0–^(3)P0 transition spectrum with a linewidth of 208 Hz is obtained.
