1550nm Narrow linewidth single-frequency laser Module-LD-PD INC

1550nm Narrow linewidth single-frequency laser Module

LD-PD's narrow linewidth single-frequency laser using an unique the semiconductor external cavity structure. The typical output bandwidth is less than 3KHz linewidth and the wavelength has low sensitivity to vibration. This device has high side-mode suppression ratio, low relative intensity noise and excellent wavelength stability for a variety of applications for harsh environment.

LD-PD's narrow linewidth single-frequency laser has its own patents, high structural stability, mature technology and it is suitable for mass production. This devise complies with Telcordia GR-468 standard and has passed the long-term reliability test.
