Under development New product LT050PS/MS Compact Laser Diode for DVD(635nm-5mW) s s Red Laser Diode General Description Sharp's red laser diodes LT050PS / LT050MS have been developed for DVD that will bring a great hope to visual media of the next generation. Model Name * LT050PS **** Single power supply * LT050MS **** Double power supply Outliine Dimensions (Unit:mm) Junction X s 90 1.0 0.4 Minitor photodiode 1 3 2 Y s Features (1) Maximum optical output : 5mW (2) Wavelength: 635nm (3) Compact o5.6mm package (4) Stable transverse mode (5) High temperature operation at 60C (7) Realizes high temperature operation by introducing a tensile strain into the multi-quantum well active layer. (8) Stable optical characteristics by developing an index guide structure of MBE method 2 times growth (9) Pair use with Sharp's OPIC* light detector IS1630 is recommended. *OPIC : OPIC (Optical IC) is a trademark of the SHARP Corporation. An OPIC consists of a light-detectinf ele,ent and signalprocessing circuit integrated onto a single chip. 0.4 o 5.6 Cap glass o 4.4 o 3.55 o 1.0 Z Reference surface 1.27 0.5 o3-0.45 2 13 s Applications * DVD players * Bar code readers * Pointers etc. [Pin connection] 1 3 s Specifications Electro-optical characteristics (Tc=25C,Po=3mW) Parameter Optical power output Wavelength Threshold current Operating current Operating voltage Radiation Parallel angle (Notice) Laser diode Monitor Photodiode 2 Symbol Ratings(TYP.)
