Precision Optics for High-Power Lasers

[image] Input Fiber Focusing Systems

Models 08-FFS-1 and 08-FFS-2 are complete opto-mechanical assemblies that provide a stable "industrial strength" means for coupling the output of high-power lasers to multimode silica fibers. All models are capable of handling several kilowatts of power (CW or average). Primarily designed for Nd:YAG lasers, these systems can, with the appropriate anti-reflection coatings, also be used with Alexandrite, Ti:Saphhire and other lasers that emit within the active spectral range of fused silica.

DPM Photonics welcomes the opportunity to discuss custom builds around the 08-FFS Input Fiber Focusing system. Please download this Request Sheet (PDF) to provide us as much information about your system as possible so we may review your needs.


  • A 3-element, air spaced aplanatic focusing optic corrected for both spherical aberration and coma.
  • Computer-designed lens elements allow for prediction of beam waist by the product of the focal length (mm) and divergence (mrad)
  • A rugged, stable, state-of-the-art Gimbal/Translation stage with alignment correction in θ, Φ, X and Y with independent X-Y adjustment on the fiber receptacle
  • SMA, LD-80 or D-80 screw in/screw out fiber receptacles (other connector types available on request)
  • Fiber alignment 56-pitch tamper resistant screws for aligning fiber face to lens axis


  • Welding
  • Cutting
  • Soldering
  • Drilling
