Recently, a domestic high-tech enterprise has made a key technological breakthrough in the field of special laser fiber, and its self-developed high-temperature resistant glue combined with special clustering process has successfully increased the high temperature resistance limit of the optical fiber end face to 1400 °C, effectively solving the pain point of the domestic ordinary optical fiber glue not being resistant to high temperature in the industry, and providing technical support for the stable operation of high-power laser equipment.

It is understood that this technology adopts multi-mode quartz fiber beams, which realize the regular arrangement of fiber end faces through fine grinding treatment, and the energy loss can be controlled within 3% in a high temperature environment, while ensuring the stability of laser power. The product spectral range covers 400-2500nm, supports multi-band laser transmission, and the core diameter can be flexibly customized between 50 microns and 1500 microns to meet the needs of different scenarios.

In terms of structural design, this type of optical fiber has excellent bending resistance, with a minimum bending radius as low as 30mm, and the branch sheath is made of flame-retardant and anti-ultraviolet materials, which can effectively block 99% of ultraviolet radiation and avoid material embrittlement and performance attenuation caused by laser irradiation. At present, related products have been widely used in LDI ultraviolet lithography equipment, semiconductor manufacturing, industrial silicon wafer testing and medical light detection equipment and other fields, providing assistance for the upgrading of the high-end equipment manufacturing industry chain.
