NAME
ML101J18, ML120G18
DESCRIPTION
ML1XX18 is a high-power, high-efficient AlGaInP
semiconductor laser which provides a stable, single
transverse mode oscillation with emission wavelength of
658nm and standard pulse light output of 100mW.
ML1XX18 has a real-index-waveguide which improves the
slope efficiency (reduction of the operating current) and the
astigmatic distance.
Also, ML1XX18 has a window-mirror-facet which improves
the maximum output power. That leads to highly reliable and
high-power operation.
FEATURES
•High Output Power: 100mW (Pulse)
• High Efficiency: 1.0W/A (typ.)
• Visible Light: 658nm (typ.)
• Low Astigmatic Distance: 1µm (typ.)

Note1: The maximum rating means the limitation over which the laser should not be operated even instant time.
This does not mean the guarantee of its lifetime. As for the reliability, please refer to the reliability report issued by
Quality Assurance Section, HF & Optical Semiconductor Division, Mitsubishi Electric Corporation.
Note2: TARGET SPEC /Condition Duty Cycle: less than 50%, pulse width: less than 100ns
