Narrow Linewidth Laser Linewidth Measurement SystemLinewidth 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 critical to the development, manufacturing and quality control of optical communication lasers. Combined with Keysight's signal analyzers and dedicated test sets, you can easily measure linewidth. Idealphotonics' narrow linewidth laser linewidth tester uses the delayed self-heterodyne beat frequency method to test the laser linewidth. When used with a 50km delayed optical fiber, it can measure lasers with a linewidth of 2kHz without the need to build a complex system.

Product features：Laser linewidth measurement down to 2kHz、 Wide wavelength range 1300-1700nm、 The interferometer and the optical receiver are in one box
