Red Laser Diode

DL-3038-033

Index Guided AlGaInP Laser Diode

Overview

Package Dimensions

DL-3038-033 is index guided 635 nm (Typ.) AlGaInP laser diode with low threshold current and high operating temperature.

Low threshold current and short wavelength are achieved by a strained multiple quantum well active layer. The lasing wavelength is 635 nm which is 8 times brighter than that of 670 nm lasers. DL-3038-033 is suitable for applications such as bar-code scanners, laser pointers and other optical information systems.

Features
