DL-3038-011
Index Guided AlGaInP Laser Diode
Overview
DL-3038-011 is index guided 635 nm (Typ.) AlGaInP laser diode.
The low threshold current and short wavelength are achieved by a strained
multiple quantum well active layer.
The lasing wavelength is the same as He-Ne gas lasers. DL-3038-011 is
suitable for laser pointers.
Features
• Short wavelength : 635 nm (Typ.)
• High output power : 5 mW CW
• Low threshold current : Ith = 40 mA (Typ.)
• Low operating voltage : Vop = 2.2 V (Typ.)
