MITSUBISHI LASER DIODES ML1XX18 SERIES FOR OPTICAL INFORMATION SYSTEMS TYPE NAME ML101J18, ML120G18 DESCRIPTION ML1XX18 semiconductor is FEATURES a high-power, laser which high-efficient provides a •High Output Power: 100mW (Pulse) AlGaInP stable, single • High Efficiency: 1.0W/A (typ.) transverse mode oscillation with emission wavelength of • Visible Light: 658nm (typ.) 658nm and standard pulse light output of 100mW. • Low Astigmatic Distance: 1µm (typ.) ML1XX18 has a real-index-waveguide which improves the slope efficiency (reduction of the operating current) and the APPLICATION astigmatic distance. Also, ML1XX18 has a window-mirror-facet which improves Portable High-Density Optical Disc Drives the maximum output power. That leads to highly reliable and Re-Writable DVD Drives high-power operation. ABSOLUTE MAXIMUM RATINGS (Note 1) Symbol Parameter Po Light output power Conditions Ratings CW 60 Pulse(Note 2) 100 Unit mW VRL Reverse voltage - 2 V Tc Case temperature - -10 ~ +70 °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.
