    MITSUBISHI LASER DIODES ML1XX20 SERIES FOR OPTICAL INFORMATION SYSTEMS TYPE NAME ML101J20, ML120G20 This type is under development. Therefore, please note that this data sheet may be changed without any notice. DESCRIPTION ML1XX20 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 140mW. ML1XX20 has a real-index-waveguide which improves the slope efficiency (reduction of the operating current) and the astigmatic distance. Also, ML1XX20 has a window-mirror-facet which improves the maximum output power. That leads to highly reliable and high-power operation. FEATURES •High Output Power: 140mW (Pulse) • High Efficiency: 1.0W/A (typ.) • Visible Light: 658nm (typ.) • Low Astigmatic Distance: 1µm (typ.) APPLICATION Portable High-Density Optical Disc Drives Re-Writable DVD Drives ABSOLUTE MAXIMUM RATINGS (Note 1) Symbol Parameter Conditions Ratings Unit CW 60 Po Light output power mW Pulse(Note 2) 140 VRL Reverse voltage - 2 V Tc Case temperature - -10 ~ +75 °C Tstg Storage temperature - -40 ~ +100 °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.
