Product Features

The characteristics of the 976-27W High reliability and wide wavelength locked range diode laser are reflected in its name. As the pump source of fiber lasers and ultrafast lasers, wavelength-locked lasers have extremely high reliability requirements, and the wave-locking performance is the parameter data that customers are very concerned about. Each of BWT’s wave-locking products is processed and produced by automated equipment, and a separate VBG coupling process is used for each chip. Therefore, the performance consistency of batch products can be guaranteed while ensuring the best wavelength locking effect;

BWT’s Sino-European R&D team has more than ten years of design, development and manufacturing experience in the field of wavelength-locked diode lasers. Rich experience supports us to provide customized laser solutions according to customer needs.
