Single Frequency Lasers
1550nm Ultra-Narrow Linewidth CW Fiber Laser
This 1550 nm single-frequency narrow-linewidth CW fiber laser is based on a fiber DFB laser cavity structure, delivering single-longitudinal-mode output with spectral linewidth ≤3 kHz and side mode suppression ratio ≥60 dB. Available with output power from 50 mW to 1000 mW in both SM (SMF-28) and PM (PM1550) fiber options, with module (M21/M31/M27) and benchtop (B1/B2) package forms. Ideal for distributed fiber sensing, LiDAR, quantum optics, and precision spectroscopy.
