As a high-quality transmission medium, optical fiber is changing our lives. It promotes the development of the information age and enables people to swim and enjoy high-definition television programs on the Internet. In the medical field, the “figures” of optical fibers can be seen in both large-scale medical diagnostic imaging devices and implantable medical device products. Due to the increase in the use of fiber optics for minimally invasive surgery, the increased demand for advanced diagnostic techniques, and the rapid development of medical fiber technology, the Medical Laser Fiber market has grown at a significant rate. The number of medical optical fiber applications including X-ray imaging, ophthalmic lasers, phototherapy, laboratory and clinical diagnostics, dental headpieces, surgical and in vitro diagnostic instruments, surgical microscopes, and endoscopy has increased significantly. In addition, the miniaturization of medical devices has also increased the demand for medical fiber technology. 1. Laser Surgery Conventional laser surgery can be used in gynecology, anorectal, surgery, dermatology, dentistry, urology, etc., for treatment such as tissue cutting, vaporization, irradiation, and so on. For body surface lesions, the laser can be transmitted with a simple lens, while for the internal lesions, fiber output is required. The output of the fiber can be installed with a spherical and cylindrical laser diffuser, and can also be filled with scattering media, so that the light Spread evenly around. Among them, the low-hydroxyl silica laser fiber can be used to transmit a 2.14μm He-Ne laser, which is currently gaining more applications in the field of laser lithotripsy. In addition, Quartz Laser Fiber surgery can also be used for oral hard tissue therapy, minimally invasive pharyngeal surgery, condyloma acuminatum and other treatments. 2. Laser Therapy Directly irradiating the affected part with a weak laser (such as a Holmium Laser, a semiconductor laser, etc.) causes a series of biological effects, thereby achieving the purpose of accelerating healing or relieving pain and other auxiliary treatments. For the treatment of small areas of the body surface or part of the cavity (such as the nasal cavity, external auditory meatus, vagina, urethra), such as super pain red light treatment instrument. 3. Photodynamic therapy Photodynamic therapy mainly uses tumor tissues and normal tissues to have different affinity properties for photosensitizers. Tumor tissues absorb and retain more photosensitizers. Photochemical reactions occur under the participation of oxygen in biological tissues when irradiated with light of specific wavelengths. The generation of singlet oxygen and (or) free radicals, destruction of a variety of biological macromolecules in tissues and cells, eventually causing tumor cell death, for therapeutic purposes. An optical fiber can transmit laser light of a specific wavelength to a diseased tissue for long-distance irradiation, and the tip can be made into various shapes.

As China's laser industry continues to undergo the process of localization, with significant improvements in the quality of domestic products, the domestic market share of laser products, including high-power laser equipment, light sources (fiber lasers, ultrafast lasers, etc.), optical components, control systems (chips, control software, and accessories), and crystal materials, has been steadily increasing in the past two years. According to data released by the General Administration of Customs, the total import and export value of "lasers, excluding laser diodes" in China from January to June 2023 amounted to 9.229 billion yuan, a 2.42% decrease compared to the same period last year. The import value was 6.859 billion yuan, a 12.05% decrease year-on-year, while the export value was 2.37 billion yuan, a 19.16% increase year-on-year. Although China still relies heavily on imports for high-end equipment, the industry of laser processing machines for various materials has made significant progress in the past six years. Domestic companies have increased their exports and actively explored overseas markets, entering a favorable development stage. With policy support, important conditions have been created for the development of high-end equipment in the industry. Source: OESHOW

With the deepening of Industry 4.0 and the concept of "Made in China 2025," more and more companies have begun to realize the importance of transformation and upgrading, especially in the automotive manufacturing industry. China's laser industry has developed rapidly and has a clear competitive advantage, with an increasing market share in the global laser market. In 2022, the total global sales of lasers reached approximately 19.3 billion US dollars, and the Chinese laser market reached 14.74 billion US dollars, with fiber lasers accounting for 51% of the domestic market. Fiber lasers are a trusted technology that can generate higher value with sufficient energy, empowering the automotive industry.

High-temperature resistant fiber faces specific challenges in various aspects when operating in high-temperature environments, commonly used in sensing, LDI, and other fields. In high-temperature conditions, conventional fibers often experience problems such as optical loss, refractive index changes, and material expansion. Here are four key challenges: Material Selection: High-temperature resistant fiber requires the use of materials with excellent high-temperature stability, such as special glasses or ceramic materials. Selecting suitable materials needs to consider factors such as chemical stability, thermal expansion coefficient, and tensile strength under high-temperature conditions. Structural Design: The structure of high-temperature resistant fiber needs to withstand the stress and deformation caused by high temperatures. Fiber design should balance strength, flexibility, and thermal stability to ensure the fiber does not fracture or lose performance in high-temperature environments. Fiber Connection and Packaging: In high-temperature environments, fiber connections and packaging must maintain stable optical transmission performance. This includes selecting fiber connectors, connection techniques, and packaging materials that can maintain good connection quality and low losses under high temperatures. Environmental Adaptability: High-temperature resistant fiber also needs to adapt to different high-temperature environmental conditions, such as industrial furnaces, high-temperature air, or high-pressure environments in aerospace applications. The high-temperature performance of the fiber requires rigorous testing and validation to ensure its stability and reliability. Hecho's self-developed high-temperature resistant fiber offers advantages such as high-temperature resistant interfaces, high power handling, high transmittance, long-term high transmittance retention, aging-resistant sheathing options, high-temperature packaging, ultra-long lifespan, and high beam collimation. These features enable reliable transmission of optical energy and signals in various specific applications under high-temperature environments.
