摘要：
To realize a neutral mercury lattice clock, an experimental setup is in developing in SIOM. With two stable cooling lasers and a new vacuum system, an enhanced cold mercury atom source is implemented based on a two-dimensional magneto-optical trap (2D-MOT). By applying a hybrid frequency stabilization method and optimization of the 2D-MOT, about 1.3x10(6) cold mercury atoms are obtained with a loading rate of 1.0x10(6) atoms/s. And a high power injection-locked Ti:sapphire laser at 725 nm is developed for optical lattice at magic-wavelength.
