NAME
ML1012R, ML1412R, ML120G2
FEATURES
DESCRIPTION
• High Power: 30mW (CW), 50mW (pulse)
• Visible Light: 685nm (typ)
ML1XX2 is a high power AlGaInP semiconductor laser
which provides a stable, single transverse mode
oscillation with emission wavelength of 685-nm and
standard CW light output of 30mW.
ML1XX2 has a window-mirror-facet which improves
the maximum output power. That leads to highly
reliable and high-power operation.

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.
Note2: TARGET SPEC /Condition Duty less than 50%,pulse width less than 1µs
