FemtoGuide Fiber

Lightcore Technologies multiphoton delivery fiber (FemtoGuide) is a flexible fiber enabling the delivery of femtoseconds and picoseconds pulses in the 400nm – 600nm and 800nm – 1700nm wavelength ranges .

FemtoGuide fiber features extremely low nonlinearity and dispersion such that >100fs pulses remain undistorted in the spectral and temporal domains.
