Laser-focused atomic deposition is a technique with which nearly resonant light is used to pattern an atom beam.To solve the problem that the result of laser-cooled atoms cannot be monitored during the 30-min depositing time,we present a three-hole mechanically precollimated aperture apparatus.A 425 nm laser light standing wave is used to focus a beam of chromium atoms to fabricate the nanoscale grating.The period of the grating is 213±0.1 nm,the height is 4 nm and the full width at half miximum is 64±6 nm.
