Products Details

Product Features

The 976-18W wavelength locking semiconductor laser features high reliability and wide wavelength locking range. The wavelength locking laser needs to ensure the best wavelength locking effect during processing. BWT uses automated equipment, so BWT uses a separate VBG coupling process for each chip. If there is a need for batch production, BWT's fully automated production equipment can ensure the performance consistency of batch products; BWT's experienced Sino-European technical team has laid a solid foundation for the design, development and manufacture of stable-wave fiber-coupled diode lasers. BWT has more than ten years of experience in the design, development and manufacturing of wavelength-locked semiconductor lasers. Since 2003, it has provided more than 100K products to hundreds of customers at home and abroad, and is now widely used as fiber lasers and ultrafast lasers the pump source. The performance of the product has been completely stable and reliable, and has been recognized by many customers.

Instructions 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 close to the middle of the pins. Soldering temperature should be lower than 260℃ and time shorter than 10 second. - Make sure the fiber output end is properly cleaned before operation of laser. Follow safety protocols to avoid injury when handling and cutting the fiber. Minimum Order Quantity: 1 Piece/Pieces Delivery Time: 2-4weeks Payment Terms: T/T
