Precise geometry High ytterbium doping concentration High laser slope efficiency Low photo-darkening High reliability coating Double-cladding Ytterbium-doped Fiber (YDF) Everfoton's Double-cladding Ytterbium-doped Fiber (YDF) is one kind of active fiber used for 1 micrometer fiber laser. Laser made with fiber cavity is extensively used in material processing, medical treatment and scientific research and other fields. Fiber laser is widely used for its advantages such as lightness, efficiency and stability, which is competitively alternative to solid state laser.

Precise control of geometric parameters Excellent birefringence High laser conversion efficiency Excellent beam quality Polarization-maintaining Ytterbium-doped Fiber Everfoton's panda type Polarization-maintaining Ytterbium-doped Fiber, based on advanced PCVD and MCVD technologies, has excellent geometric and birefringent properties, which can effectively reduce the nonlinear effect in the optical system. As a gain fiber, it has high optical conversion efficiency and outstanding beam quality, which is widely used in ultrashort pulse precision processing, lidar and other fields.

Precise geometry Low splice loss Low NA that ensures excellent beam quality Passive Fiber Everfoton's double/single-cladding Passive Fiber is optimized precisely to match the DC-GDF series, with low splice performance. The fiber is widely used in industrial, medical and other fields. Large core and high NA multi-mode fiber can be used to pump source output and high power output.

Precise control of geometric parameters Excellent birefringence Matching active ytterbium-doped polarization-maintaining fiber with good fusion compatibility Polarization Maintaining Passive Double-cladding Fiber Everfoton's panda type Polarization Maintaining Passive Double-cladding Fiber, adopting core and stress rod manufactured through the advanced PCVD process, has accurate refractive index distribution and excellent geometric and birefringent properties. Using special coating with a low refractive index, high NA (numerical aperture > 0.46) double-cladding transmission is achieved. Meanwhile, large mode field diameter ensures good connection with other passive double-cladding fibers, and perfectly matches PM ytterbium doped fiber, which is very helpful to ultrafast laser processing and reducing high pulse nonlinear effect.

Flat-top beam profile Beam uniformity-reduces hot spots Ultra-low insertion loss Effective luminance conservation Excellent compatibility-compatible with most optical fiber interconnection systems Products can be used at different power levels Homogenized Fiber The special fiber homogenization technology of Everfoton adopts step profile fiber design to ensure a high degree of compatibility with traditional fiber. With special design, the mode excitation in the fiber core can be adjusted to convert the input beam into a uniform flat-top beam profile while maintaining efficient optical propagation and a ultra-low insertion loss. Homogenized fiber can be efficiently integrated with existing optical systems, and used in laser cladding, laser cleaning, laser welding, uniform illumination, spectroscopy, power supply, medical care and other fields.
