Hitachi HL6312G Algainp laser diode Datasheet

HL6312/13G
AlGaInP Laser Diodes
Description
The HL6312/13G are 0.63 µm band AlGaInP laser diodes with a multi-quantum well (MQW)
structure. Wavelength is equal to He-Ne Gas laser. They are suitable as light sources in bar code
readers, laser levelers and various other types of optical equipment. Hermetic sealing of the package
achieves high reliability.

Polarization direction
The polarization direction is TM mode. The polarization direction of 0.63 µm LD’s is different from
that of 0.83/0.78/0.67 µm LD’s. The polarization direction of 0.63 µm LD’s is illustrated in the figure
below.
