Tunable Light Sources

GouMax TLS-1000 tunable light sources are new-generation high performance continuous wave (CW) tunable laser sources for use in various single band or combined band windows, ranging from 1050 nm to 1660 nm. The innovative design employs the state-of-the-art tunable technology and gain continuation in wide wavelength range. With no moving parts, the voltage-controlled wavelength tuning enables rapid wavelength switching over the whole operating wavelength window.

This datasheet describes and defines GouMax's low coherent CW tunable light sources with applications to test and measurement. They provide fast wavelength tuning, high power output, and high power stability. GouMax tunable laser products support O-band, E-band, S-band, C-band, L-band, and other single-band operation, as well as combined adjacent bands. A full-band tunable laser is also available, covering 1250~1650 nm wavelength range, with seamless wavelength tuning.

System control and communication is provided though the RS232 interface, which allows users to dynamically set operating wavelength with ease.
