Laser Diodes & Sources
The 785nm series laser diodes are fabricated in a hermetically sealed 14-pin butterfly package. The laser diodes contain a monitor photodiode, thermoelectric cooler (TEC), and a thermistor to secure high-quality laser performance. Our laser products are Telcordia GR-468 qualified and in compliance with RoHS Directives. A matching driver is available in either a compact module or benchtop turn-key unit. Fabry Perot single mode laser. CW or pulsed operation. Operating temperature range -10°C to +70°C. Wavelength/temperature coefficient 0.2nm/°C Built-in monitor photodiode, thermo-electric cooler, and thermistor. Single mode (Corning HI780, NA=0.14, MFD=4.5um@780nm, 5um@850nm) or polarization maintaining (PM) fiber pigtail. Optional FC/PC or FC/APC connector.

Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
785nm Butterfly Laser Diode - 250mW: Laboratory optical integration depends on preserving the optical budget through the complete path. The 785nm wavelength specification sets source and detector compatibility. The fiber/interface entry (Hi780, PM780) must match the connected components.

Technical FAQ
Fiber Type: Hi780, PM780 · Fiber Buffer: 900µm Tube. Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
Wavelength: 785nm. Check the Laser Diodes & Sources passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
Share your wavelength, fiber type, connector, power handling and control requirements and we will qualify the matching configuration and part number.
