TYPE
NAME
ML101J22, ML120G22
DESCRIPTION
ML1XX22
is
FEATURES
a
high-power,
high-efficient
•High Output Power: 180mW (Pulse)
AlGaInP
semiconductor laser which provides a stable, single
transverse mode oscillation with emission wavelength of
• High Efficiency: 0.95W/A (typ.)
658nm and standard pulse light output of 180mW.
• Low Aspect Ratio (θ⊥ / θ//): 1.8 (typ.)
• Visible Light: 658nm (typ.)
ML1XX22 has a real-index-waveguide which improves the
slope efficiency (reduction of the operating current) and the
• Low Astigmatic Distance: 1µm (typ.)
astigmatic distance.
APPLICATION
Also, ML1XX22 has a window-mirror-facet which improves
the maximum output power. That leads to highly reliable and
Portable High-Density Optical Disc Drives
Re-Writable DVD Drives
high-power operation at 75 °C.

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.
