Laser collimation of Cr atomic beam using a transverse Doppler cooling scheme is studied. The frequency of laser is stabilized at 5±0.26MHz below the 7S3→7PO452Cr transition. The shortest size of the laser cooling beam is computed theoretically to be 13.7mm. Accordingly a Cr beam was collimated using a transverse Doppler cooling scheme. We obtained that the transverse distribution of Cr beam is less than 1/3 of the uncooled beam.
