Ultra Narrow Linewidth Laser Module 1550nm 3kHz
The 1550nm narrow linewidth laser module is a low noise laser source. The unique design of the optical path structure ensures the single-frequency operation of the laser, while using a unique temperature control technology and anti-vibration structure to eliminate the influence of external temperature changes and vibration on the output wavelength, thus achieving a stable single longitudinal mode, narrow linewidth single-frequency laser output. The single-frequency narrow linewidth fiber laser has excellent performance, with the output spectral linewidth reaching kHz level, ultra-low frequency noise and intensity noise, and the output spectral edge-mode rejection ratio reaching 60dB or more. In addition, the unique design of the high-strength package ensures that the fiber laser module can better adapt to different application environments and achieve stable single longitudinal mode output without mode hopping under external conditions such as temperature change, vibration and shock.
