80mW 1550nm DFB Laser Diode
These single frequency 1550nm DFB laser diodes offer up to 80mW of laser output power with a very narrow line width emission profile of 150 kHz. These lasers are also wavelength tunable.
DFB lasers are used in applications such as sensing, telecommunications, spectroscopy and atomic physics. They employ Bragg diffraction gratings in the active gain region of the semiconductor to form a waveguide. These 1550nm devices are an industry standard butterfly package with a "Type 1" pin configuration. The butterfly package is electrically floating, allowing for mounting flexibility and bias current source selection flexibility. The butterfly package includes an internal 10K thermistor, a TE cooler and a monitor photodiode.
Features:
Single Mode Emission Spectral
150kHz Laser Spectral Line Width
Single Mode or Polarization Maintaining Fiber, Terminated with FC/APC
14-Pin Butterfly Package; Integrated TE Cooler, Thermistor, Monitor PD
