Continuous laser module

continuous waveCWfiber

Product description
YOEC single-frequency narrow linewidth laser module is engineered for high-precision photonics applications that require exceptional frequency stability, ultra-narrow linewidth and low phase noise. The module delivers a highly coherent single-frequency output with a typical linewidth below 3 kHz and a center wavelength around 1550.12 nm. Its compact footprint, low power consumption and robust control enable straightforward integration into fiber-based and free-space optical systems.
