The PL-VCSEL-1-A81 760nm VCSEL is a vertical emitting MOVPE grown GaAsP/AlGaAs Single Mode diode laser. The chips are mounted in TO39 can. Wavelength tuning can be achieved via laser current and temperature tuning. package with TEC and PD Built in. It is special designed for TDLAS Application. Good Narrow linewidth and wide tunability with TEC made it a great low cost choice for Analyzer measures oxygen manufacture.
