摘要：
A bar code scanning device, system and method that utilizes one or more vertical cavity surface emitting laser diodes for producing at least one laser beam, where the vertical cavity surface emitting laser diodes are disposed on a substrate, and wherein the produced laser beam is substantially an essential single spatial mode laser beam. The bar code scanning device, system and method of present invention also comprise a photodiode attached to the substrate and arranged to receive at least a portion of the beam of light reflected off the scanned bar code or symbol.
