1550nm Narrow Linewidth Single Frequency Semiconductor Laser

Short Description:

The 1550nm narrow linewidth single frequency semiconductor laser of Connet is a low-noise semiconductor laser module with excellent performance. The output spectral linewidth can be less than 5kHz and the coherent length is long with ultra-low relative intensity noise (RIN). Comparing with most commercial fiber lasers, the CoSF-SC single frequency semiconductor lasers have better wavelength stability and can better adapt to various harsh application environments for the compact and robust package.
