Narrow Linewidth Laser with Driver

High Performance Constellation – BF9C series

Constellation Series – Single Frequency Narrow Line Width Lasers

 

The DL-BF9C Constellation product series uses DenseLight’s proprietary 14-pin butterfly package manufacturing process, enabling improved performance of the external cavity laser to give high PER performance, high stability line width, low RIN < -155 dB/Hz & low phase noise performance.

This series features a narrow linewidth of <50Khz, & <200 Khz. option & a minimum output power of 10 mW. The Constellation ILM is suitable for embedded designs or standalone uses in a wide range of communication and sensing application. When using the Constellation series, the fiber optic systems will operate at a premium performance level
