Red Laser Diode

DL-3147-141(-241)

Index Guided AlGaInP Laser Diode

Overview

DL-3147-141(-241) is index guided 645 nm (Typ.) AlGaInP laser diode with low threshold current and high operating temperature. The low threshold current and high operating temperature are achieved by a strained multiple quantum well active layer. DL-3147-141(-241) is suitable for applications such as bar-code scanners, optical disc systems and other optical information systems.

Features

∙ Short wavelength	: 645 nm (Typ.)
∙ Low threshold current	: Ith = 45 mA (Typ.)

∙High operating temperature : 5 mW at 60°C

∙TE mode
