Abstract :Mercury is a promising candidate for the optical lattice clock, due to its low sensitivity to the blackbody radiation. We develop a single folded beam magneto-optical trap for the neutral mercury optical lattice clock, with a 253.7 nm frequency quadrupled laser. Up to $1.7\times10^{6}$ ($^{202}$Hg) or $1.5\times10^{6}$ ($^{199}$Hg) atoms can be captured, and the atom temperature is lowered to 170 μK ($^{202}$Hg) or 50 μK ($^{199}$Hg). The cold atom signals of all six rich abundant isotopes are observed in this system.
