High Damage Threshold Fibers

Our High-Power Density Fibers have a pure silica core and a silica cladding, providing an ultra-high damage threshold. In addition, a chemically bonded hard coat adds high strength and increases fatigue resistance. The fibers’ low OH- content makes them most suitable for operation in the 500–2100 nm wavelength ranges. Fibers in this category, offered in 365 and 550 µm core diameters, can tolerate peak power density levels nearing 1 GW/cm2.

Moderate Damage Threshold Fibers

Our Moderate Power Density Multimode Fiber features a pure silica core and a bonded hard polymer cladding, adding strength and increasing fatigue resistance. The fiber’s high NA of 0.37 allows greater light coupling efficiencies and allows for added bend insensitivity. This fiber is available in 600 µm core diameter, and is most suitable for use in the 500 to 1100 nm wavelength range. Limited to maximum power densities of about 100 kW/cm2.
