Narrow linewidth laser linewidth measurement system/linewidth analyzer 1300-1700nm (linewidth 2-5000KHz input 0.2-20mW)

The laser linewidth measurement system is a simple and accurate laser diode linewidth measurement system. The evaluation of laser linewidth is crucial for the development, manufacturing, and quality control of optical communication lasers. By combining Keysight's signal analyzer and dedicated test set, you can easily measure line widths. Idealphotonics' narrow linewidth laser linewidth tester uses a delayed self heterodyne beat frequency method for laser linewidth testing. Paired with a 50km delayed fiber, it can measure laser linewidths of 2kHz without the need to build complex systems.
