The distributed feedback (DFB) laser was designed for use in scientific and industrial applications. The laser is assembled into a 14-pin butterfly package with an optical isolator, a monitor PD, and a thermo-electric cooler. This device has a center wavelength output at 1180nm and delivers 30mW from Ex-fiber. The laser is also available at 1120nm center wavelength; inquire about part number The QLD1161-2030.
