  The dark matter puzzle is one of the most important fundamental physics
questions in 21 century. There is no doubt that solving the puzzle will be a
new milestone for human beings in the way of deeper understanding the mother
nature. Here we propose to use the Shanghai laser electron gamma source (SLEGS)
to search for dark matter candidates particles, including dark pseudo scalar
particles, dark scalar particles, and dark photons. Our simulations show that
electron facilities like SLEGS with some upgrading could be competitive
platforms in searching for light dark matter particles with mass under tens of
keV.
