DenseLight DL-CLS series is a cooled narrow linewidth laser in 14-pin BTF/DIL package with a single frequency emission. The DL-CLS laser family is based on proprietary external cavity laser design utilizing a built-in fiber Bragg grating, offering very stable performance of lasing wavelength, narrow spectral linewidth and excellent SMSR.
The as-built lasing wavelength can be specified precisely to 1nm. The device can directly intensity modulated up to 622MBPS. Typical output power is up to 10mW CW, with Pulse Power up to 50mW.

Note:
Typical linewidth can be narrowed down to Ultra-Narrow Linewidth < 5KHz when using Integrated InfraRed Light Module (I
2LM) BF-series with high precision laser driver and temperature controller.
Further precision wavelength (DOWN TO PICOMETER RANGE) CAN BE ACHIEVED THROUGH TUNING THE INTERNAL TEMPERATURE OR DRIVE CURRENT.
