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 continua-
tion 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 high coherent CW tunable light sources with applica-
tions 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.

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