DL-4038-021
High Power AlGaInP Laser Diode
Overview
DL-4038-021 is a high power 635 nm (Typ.) AlGaInP laser diode with low
threshold current. High output power and low threshold current are
achieved by use of a strained quantum well active layer. The lasing
wavelength is the same as that of the He-Ne gas lasers. DL-4038-021 is
suitable for applications such as laser printers, line markers and other
optical information systems.
Features
•Short wavelength : 635 nm (Typ.)
•High output power : 10mW CW
•Low threshold current : Ith = 35 mA (Typ.)
•Low operating voltage : Vop = 2.2 V (Typ.)
