FemtoFiber ultra Mini2P

Femtosecond fiber laser for Mini2P

  • No mirror alignment, just automated fiber coupling
  • Simple fiber exchange with safeguard monitor to make misalignment an impossibility
  • Clean Pulse Technology

In  the FemtoFiber ultra Mini2P, TOPTICA combines a polarization-maintaining hollow-core fiber suitable for Mini2P (miniaturized 2-photon microscope) with TOPTICA’s proprietary COOL technology:  COOLAC offers hands-off, automated fiber coupling that eliminates manual alignment at installation, optimizes fiber coupling efficiency at the touch of a button, and provides a safeguard monitor to make misalignment an impossibility. With COOLAC, exchange of the Mini2P-fiber is easy and fast, and can be peformed by the user.

Additionally, an integrated AOM for fast power modulation, software-controlled dispersion precompensation (GDD) and TOPTICA’s unique Clean Pulse Technology complete the laser system.
