Ytterbium-Doped Fiber Amplifier, Rackmount (YDFA)

Data Sheet

Product Overview

The Ytterbium-Doped Fiber Amplifiers (YDFA) series utilize Ytterbium (Yb) doped fiber technologies to achieve optical amplification in 1064 nm wavelength range. The all-fiber-based product are extremely reliable and requires no routine maintenance. Commercially proven 915 nm pump laser sources ensure long-term reliability. RS-232 computer interface allows for remote control via LabVIEW software. These units are well-suited for Bio-medical, SHG, fiber sensors, LIDAR pulse amplification and free space communications.
