DL-3038-033
Index Guided AlGaInP Laser Diode
Overview
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
• Short wavelength : 635 nm (Typ.)
• Low threshold current : Ith = 30 mA (Typ.)
• High operating temperature : 5 mW at 50°C
• Low operating voltage : Vop = 2.2 V (Typ.)
