Single Crystal Fiber (SCF)

Fibercryst pioneered Single Crystal Fiber (SCF) technology, the best solution for short pulse amplification; it is used throughout its product lines. 

A (SCF) is a single-crystal with a long length, a small diameter and attractive light guiding properties.  Single crystal fibers are typically 1 mm in diameter and 30 to 50 mm long and generally produced in Nd:YAG or Yb:YAG. 

In a SCF amplifier, the pump beam is focused In a 400 µm diameter spot near the crystal fiber input. The highly divergent beam is then guided by total internal reflection and refocused again in the gain medium. The laser beam is unguided through the crystal, like in a classical rod, with a typical diameter of 400 µm at 1/e². The high refractive index of the crystal naturally limits the divergence of the beam.
