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.

ML1XX2 is a high power AlGaInP semiconductor lase
r
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.
