Product Features
Since 2003, BWT has nearly 20 years of experience in R&D and production of fiber laser pump sources, and has a good reputation in the industry. BWT's fiber lasers also use self-developed pump sources, which further proves the stable performance and high reliability of BWT's pump sources. In the product development stage, BWT will conduct various inspections on suppliers, select high-quality raw materials, and then put them into production after ensuring high quality. Fully automated production equipment is used in the production process to ensure the performance consistency of batch products.Main Features
