GouMax developed CW tunable light sources with applications to test and measurement equipment. It provides fast wavelength tuning, high power output, and high power stability.

The GouMax tunable lasers are a new-generation high performance continuous wave (CW) tunable laser source 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.
