1550nm narrow linewidth single frequency semiconductor laser module 10mW

The narrow linewidth single frequency laser of LD-PD adopts a unique semiconductor external cavity structure. The typical output bandwidth is less than 3kHz linewidth, and the sensitivity of wavelength to vibration is low. This device has high edge mode suppression ratio, low relative intensity noise, and excellent wavelength stability, making it suitable for various applications in harsh environments. LD-PD narrow linewidth single frequency laser has independent technical recognition, high structural stability, mature technology, and is suitable for mass production. This product complies with Telcordia GR-468 standard and has passed long-term reliability testing.
