DESCRIPTION
The narrow line width module is compact laser modules employing the high-performance compact Distributed Bragg Reflection (DBR) Cavity Fiber Laser, which features mode-hop free and very narrow linewidth. It provides a stable, easy-to-use, low cost alternative to other ECL lasers. The module uses reliable, qualified and industry proven components, and employs special temperature control circuitry and anti-shock structure to ensure stable performance under flexible circumstance . External control can be accomplished via a standard software interfaces.
