摘要： A polarization-type saturated absorption spectrum set-up for {}^{87}Rb atom laser cooling and trapping has been established in our laboratory. By changing the polarization components and optical power, enhanced absorption of the transition 5S_{1/2} F=2→5P_{3/2}F′=3 was observed with other transitions and cross-over resonance staying unvaried.
