Fiber Coupled OEM Lasers

OEM fiber coupled lasers


  • 375nm to 1550nm
  • Singlemode, polarization maintaining, multimode fibers
  • Temperature stabilized
  • High stability
  • Low power requirements


The SRT-F OEM Series of fiber coupled lasers are temperature controlled to provide a highly stable laser with excellent beam quality. A range of discrete wavelengths are available from 375nm to 1550nm.

Lasers are coupled to singlemode, polarization maintaining or multimode fiber with high output powers from the fiber end. The laser body contains the laser, thermistor, TE cooler, heat sink and coupling optics in a compact package. Drive electronics are separate from the laser head making for a more compact device.

Two choices of fiber coupled lasers are available. One with a spectral bandwidth of <2nm and the other with a spectral bandwidth <0.1nm. Please call for details.

Output can be collimated with our FC Series of fiber collimators with adjustable focus. They are available with apertures from 6mm to 45mm. Please see the Fiber Collimator data sheet.


Lasers can be customized to include fiber couplers/splitters, fiber collimators, combining 2-4 wavelengths to one output for an all fiber solution, combine detection and add other optical devices onto a common platform. Higher output power lasers and other wavelengths are also used to create all fiber optical engines. Special environments and conditions can be accommodated as well.
