Product Features
976nm 60W high reliability and wide wavelength locked range diode laser is used as a pump source for fiber lasers and ultrafast lasers, featuring high reliability and wide wavelength locking range. Wavelength locking products meet customers' needs for fixed wavelength applications. BWT's Sino-European R&D team has more than ten years of design, development and manufacturing experience in the field of wavelength-locked semiconductor lasers. The R&D personnel use a separate VBG coupling process for each chip to ensure the best wavelength locking effect; and automated equipment is used in the production process to ensure the performance consistency of batch products. BWT provides customized services for wavelength locking products. Other wavelength or power customization services are available.Main Features
