A0020A Laser Linewidth Test System is a simple and accurate test system for measuring the line width of laser diodes. Evaluating a laser's linewidth is critical to the development, manufacturing, and quality control of optical communications lasers.
Combined with Keysight signal analyzers and specialized test equipment, you can easily measure linewidth.
Key Features:
- Laser linewidth measurement down to 40 kHz.
- Wide wavelength range of both C and L bands.
- Interferometer and optical receiver in one box.
