MITSUBISHI LASER DIODES ML1XX27 SERIES FOR OPTICAL INFORMATION SYSTEMS TYPE NAME ML101J27 This type is under development. Therefore, please note that this data sheet may be changed without any notice. DESCRIPTION ML1XX27 is FEATURES a high-power, high-efficient •High Output Power: 350mW (Pulse) AlGaInP semiconductor laser which provides a stable, single transverse mode oscillation with emission wavelength of • High Efficiency: 0.95W/A (typ.) 658nm and standard pulse light output of 350mW. • Low Aspect Ratio (θ⊥ / θ//): 1.7 (typ.) • Visible Light: 660nm (typ.) ML1XX27 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, ML1XX27 has a window-mirror-facet which improves the maximum output power. That leads to highly reliable and Portable High-Density Optical Disc Drives Re-Writable DVD Drives high-power operation at 75 °C. ABSOLUTE MAXIMUM RATINGS (Note 1) Symbol Parameter Conditions Ratings Po Light output power VRL Unit CW 130 Pulse(Note 2) 350 Reverse voltage - 2 V Tc Case temperature - -10 ~ +75 °C Tstg Storage temperature - -40 ~ +100 °C mW 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.
