ML1XX8 SERIES
FOR OPTICAL INFORMATION SYSTEMS
TYPE
NAME
ML101J8, ML120G8
FEATURES
DESCRIPTION
ML1XX8 is a high power AlGaInP semiconductor laser
which provides a stable, single transverse mode oscillation
with emission wavelength of 660-nm and standard CW light
output of 40mW.
• High Output Power: 40mW (CW) , 60mW (Pulse)
• Visible Light: 660nm (typ.)
APPLICATION
High-Density Optical Disc Drives
DVD(Digital Versatile Disc)-RAM Drive
ML1XX8 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.
