DL-3147-041
Index Guided AlGaInP Laser Diode
Overview
DL-3147-041 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-3147-041 is suitable for applications such as bar-code
reader, 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
