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
