TYPE
NAME
ML60125R, ML601J25
MITSUBISHI LASER DIODES
DESCRIPTION
ML6XX25 is a high power AlGaAs semiconductor
laser which provides a stable, single transverse
mode oscillation with emission wavelength of
785nm and standard light output of 30mW.
ML6XX25 is produced by the MOCVD crystal
growth method which is excellent in mass
production and characteristics uniformity . This is
a high -performance , highly reliable , and long
life semiconductor laser.

Note1: The maximum rating means the limitation over which the laser should not be operated even instant time,
and this does not mean the guarantee of its lifetime.As for the reliability,please refer to the reliability report from Mitsubishi
Semiconductor Quality Assurance Department.
