Electric Tunable Filter LaserTunable Fiber Lasers of WLTL-200-series are built on proprietary design. The lasers are consisting mainly of a gain block and frequency selection engine. Each of the elements is configurable to specific requirements, which leaves abundant options to implement variations of tuning range and optical output power. Wavelength tuning is achieved by a micro motor controlled with a PC through a USB interface. Fast setup, small foot print, fast sweep, wide tuning range and availability over X-, O-, S-, C-, and L-bands enable the lasers being cost-effective sources for R&D and lab purposes of various tests related to wavelength measurements such as DWDM component, fiber Bragg gratings and FGB sensor interrogation.
