The fiber laser uses doped glass fiber as the gain medium and fiber coupled semiconductor laser as the pump source to excite the laser through the resonator.
The core components of the fiber laser pump source include:
• Prefabricated gold tin aluminum nitride substrate material, with its high thermal conductivity, thermal expansion coefficient and chip matching, high reliability advantages are widely used in laser diode chip packaging;
• Fast axis collimator (FAC), slow axis collimator (SAC), etc., provide basic and efficient solutions for pump source beam collimation;
• The focusing lens can accurately couple the collimated and bunched light spots to the output fiber of the pump source;
• The optical coated fiber transmits laser energy to the gain medium to achieve the functional output of the fiber laser.
Brandnew provides prefabricated gold tin aluminum nitride substrate materials for fiber laser pump sources. With years of experience in the application of product eutectic bonding technology, Brandnew has optimized the optimal thermal management design, thickness design and material thermal expansion coefficient (CTE) matching design for each layer of materials from the demand side, and finally achieved low thermal resistance and low stress packaging to ensure higher power output of the device.
Brandnew provides high precision aspherical, micro - and nano-scale microoptics for fiber laser pumping applications. The fast axis collimator can calibrate 92% of the laser output power to the divergence Angle range of ±2.2 mrad, and 94% of the laser output power to the Gaussian distribution range (side peaks are negligible). The slow axis collimator uses high refractive index materials, is lighter and thinner, meets the needs of high-end collimation performance, and the finished product tolerance is small, especially suitable for automatic assembly production line.
In addition, Brandnew supplies other components such as focusing lenses and coated fibers for fiber laser pump sources.
Brandnew leads the manufacturing system with the concept of manufacturing excellence, with advanced production management tools and automation equipment, to achieve high efficiency, high quality and low cost.
The mature physical vapor deposition process and the mass production mode of "from wafer processing to single piece", supplemented by a perfect quality system, ensure the reliability of prefabricated gold tin performance and the consistency of mass production.
The unique wafer-level synchronous structuring technology enables the production of tens of thousands of microoptical lenses on a single wafer for high volume production and high consistency. Brandnew's self-developed and established optical coating capabilities not only meet the needs of its own products for optical coating, but also provide optical coating technology services; Technological innovation and the introduction of automation in the process of precision cutting, cleaning and inspection have enabled the optimization of the entire process to meet the needs of customers for mass delivery and better serve the growing customer base around the world.
