Product Features
With more than 20 years of fiber coupling technology and more than 10 years of wavelength locking technology, BWT provides professional solid-state laser pump source products for domestic and foreign customers, covering a variety of products with different specifications at 808nm, 878.6nm, and 888mn. It is applied to various solid-state lasers and ultra-fast laser pump sources, and the product performance has been widely recognized by users at home and abroad. In order to introduce international standards, BWT established a research and development center in Germany in 2020. The introduction of the European team, the experienced China-Europe R&D team greatly shortens the time for product development and upgrade iterations. Can more actively meet customer product needs.Main Features
Wavelength：808nm Output power: 150W Fiber core diameter: 200/400μm Optical fiber numerical aperture：0.22 NA Feedback protection：1020nm-1200nm Applications: Solid-state laser pumping Medical application Material processingInstructions for use
- Avoid eye and skin exposure to direct radiation during operation. - ESD precautions must be taken during storage, transportation and operation. - Short-circuit is required between pins during storage and transportation. - Please connect pins to wires by solder instead of using socket when operation current is higher than 6A. - Soldering point should be closeto the middle of the pins. Soldering temperature should be lower than 260℃ and time shorter than 10 second.| Specifications (25°C) | Symbol | Unit | Minimum | Typical | Maximum | |
