Description

The 269-type pump laser module represents a family of thermoelectrically cooled, high-power lasers. They are designed as continuous-wave (CW) optical pump sources for dense wavelength-division multiplexing (DWDM) EDFA applications.

The laser modules incorporate a high-power, quantum- well laser chip that achieves fiber powers up to 280 mW.

An integral thermoelectric cooler (TEC) stabilizes the laser at room temperature and, combined with a hermetic environment, allows the 269-Type device to achieve high-power operation over the extended temperature range of 0 to 75 . An internal InGaAs PIN photodiode, mounted behind the laser diode, functions as the laser detector and monitors light emissions from the rear facet of the laser.

The 269-type module is offered in a 14-pin, hermetic butterfly package.
