Abstract

We present our experiment on magnetic field induced spectroscopy of the ¹S_0-³P₀ transition of ⁸⁸Sr atoms with a 10 Hz linewidth laser. The ⁸⁸Sr atoms are cooled by two stage laser cooling. After the second stage narrow line laser cooling, the temperature of the atoms is reduced to ∼3 μK. 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/cm ² is used to probe the ⁸⁸Sr atoms in the lattice. By means of a magnetic field of ∼1 mT and a probe laser with 50 ms pulse and ∼6 W/cm² intensity, the Doppler free ⁸⁸Sr ¹S _0-³P₀ transition spectrum with a linewidth of 208 Hz is obtained.
