ALCOR Series <140fs, 920nm, 2W QCW Fiber Laser

ALCOR Series produces high-average power at 920nm with ultrashort femtosecond (fs) pulses (down to <140fs) at a high repetition rate (80MHz standard, others optional) in an ultra-compact and robust format.

ALCOR offers best-in-class performance within a compact, air-cooled package. Available at power levels from 1 to 2W at a fixed central wavelength of 920nm and with pulse duration <140fs as standard. This quasi continuous wave (QCW) fiber laser is ideally suited to applications in biophotonics and in particular two-photon microscopy.

The ALCOR can be supplied in a single head configuration or as a dual head system with the second wavelength in the 1micron region. Group delay dispersion pre-compensation (variable down to -30 000fs2), F-sync for fine-tuning the repetition rate for synchronization with any third party master  device are available as standard, together with customisation to shorter pulse duration of <120fs as an options.


  • Central Wavelength 920nm
  • Customisation of central wavelength from 915 to 930nm
  • Repetition rate 80MHz
  • High average power from 1W to 2W
  • <140fs (standard), <120fs (customisation)
  • Group delay dispersion (GDD) pre-compensation
