ML1XX21 SERIES
FOR OPTICAL INFORMATION SYSTEMS

TYPE NAME

ML101J21
FEATURES
a high-power, high-efficient AlGaInP •High Output Power: 160mW (Pulse) • High Efficiency: 0.95 W/A (typ.) • Visible Light: 658nm (typ.) • Low Aspect Ratio (θ⊥ / θ// ): 1.8 (typ.) • Low Astigmatic Distance: 1 µm (typ.)

DESCRIPTION
ML1XX21 is semiconductor laser which provides a stable, single transverse mode oscillation with emission wavelength of 658nm and standard pulse light output of 160mW. ML1XX21 has a real-index-waveguide which improves the slope efficiency (reduction of the operating current) and the astigmatic distance. Also, ML1XX21 has a window-mirror-facet which improves the maximum output power. That leads to highly reliable and high-power operation.

FOR OPTICAL INFORMATION SYSTEMS
DESCRIPTION
ML1XX21 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 160mW.
ML1XX21 has a real-index-waveguide which improves the
slope efficiency (reduction of the operating current) and the
astigmatic distance.
Also, ML1XX21 has a window-mirror-facet which improves
the maximum output power. That leads to highly reliable and
high-power operation.
