Designed for barcodescanning applications, the 670nm Model SLD1121VS laser diode has an aluminum gallium indium phosphide quantumwell structure. A silicon submount operates as the photodetector. This laser diode consumes 25% less power than previous versions. Typical threshold current levels are 40 mA. Optical power output is 5 mW in a TEM00 beam pattern. The device is available in a 5.6mm flatto¥package that requires 25% less volume than Sony`s 9mm laser diodes. A photodiode is included to monitor optical power output.
