    • 1550nm Ultra‑Narrow Linewidth Tunable Semiconductor Laser Module

    This narrow linewidth single‑frequency laser module utilizes a unique external‑cavity semiconductor structure. It achieves a typical output linewidth of less than 3 kHz and exhibits low sensitivity to vibration‑induced wavelength fluctuations. The device features high side‑mode suppression ratio (SMSR), low relative intensity noise (RIN), and excellent wavelength stability, making it suitable for a wide range of demanding environmental applications.

    Product features：Polarization‑maintaining output；ITU‑T 1530–1565 nm custom wavelengths available；Frequency tuning range: 5 GHz

    Part Number：MP-NLFMM-1550-E-1-PA-A-M-PZT

    Application area：Lidar | Fiber‑optic communications | Coherent sensing
