a fused silica core are the material of choice for laser beam
transmission. The low OH content and the uniform refractive
index guarantees low beam distortion and low absorption in the
VIS-IR wavelength range of 400 nm–2400 nm.
The cladding consists of fluorine-doped fused silica and defines
the beam-guiding properties and the numerical aperture of the fiber.

are available on request.
Tailored to the various applications the fibers are available with
different coating and jacket materials. Silicone and hard-clad
(fluorine-doped high-temperature acrylate) enables high power
laser beam transmission with average power levels of up to
several kilowatts. For both materials the refractice index lower is
lower than the refractive index of the fiber cladding. Therefore
radiation not confined within the fiber core will propagate along
the fiber as cladding modes. Special connectors are available to
remove or strip these cladding modes.
Fiber Optics has performed extensive research to experimentally
determine the laser beam damage threshold for the
fiber and coating materials using laser probe beams and can
therefore assist customers to exactly find the right product.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_single_image image=”3376″ img_size=”large” alignment=”center” style=”vc_box_border” border_color=”peacoc”][vc_single_image image=”3377″ img_size=”large” alignment=”center” style=”vc_box_border” border_color=”peacoc”][vc_single_image image=”3379″ img_size=”large” alignment=”center” style=”vc_box_border” border_color=”peacoc”][/vc_column][/vc_row]
