ML101J22

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

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.
