Triple-core Ytterbium-doped Double Clad Optical Fiber

INTRODUCTION
Triple-core Yb-doped double clad fiber can let high-power multi-mode pump diode couple energy into the active core without additional complex optical components and without interrupt the laser output path.
 

APPLICATIONS
The YBDCTC125 is a single mode Yb-doped core fiber with two pump core in a Double Clad structure for lasers operating in 1-100W output power range. It can be economically pumped by 915 & 975nm diode laser.Typical operating wavelength is at 1060~1100nm.
