Broadband Ultralow-Noise Single-Frequency Fiber Laser
The broadband ultralow-noise single-frequency fiber laser uses a distributed Bragg reflector (DBR) cavity with multidimensional active and passive suppression technologies to produce ultralow relative intensity noise across a broad frequency band. Narrow-linewidth single-frequency output combines high power stability with low intensity noise. It is especially suitable for noise-sensitive applications such as precision coherent detection, distributed fiber sensing and precision interferometry.
