Fiber output 780 nm single frequency laser

Short Description:

To meet the demands of the atomic physics and quantum physics based on Rb atom, Erbium group has developed fiber output 780 nm laser with maximum power of 2W using waveguide frequency doubling technique. Due to Handling, low drift, anti-vibration and other excellent environmental adaptability, EFA-SSHG-780nm has been used in out laboratory experiments of Rb atom interferometer and has been frequency stabilized with saturated absorption spectrum for several months.
