DESCRIPTION
ML1XX21
is
FEATURES
a
high-power,
high-efficient
•High Output Power: 160mW (Pulse)
AlGaInP
semiconductor laser which provides a stable, single
transverse mode oscillation with emission wavelength of
• High Efficiency: 0.95 W/A (typ.)
658nm and standard pulse light output of 160mW.
• Low Aspect Ratio (θ⊥ / θ//): 1.8 (typ.)
• Visible Light: 658nm (typ.)
ML1XX21 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, ML1XX21 has a window-mirror-facet which improves
the maximum output power. That leads to highly reliable and

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.
