LT050PS/MS
Compact Laser Diode for DVD(635nm-5mW)
■ 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
■ Features
(1) Maximum optical output : 5mW
(2) Wavelength: 635nm
(3) Compact ø5.6mm package
(4) Stable transverse mode
(5) High temperature operation at 60˚C
(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.
