Shenzhen Raybow Optoelectronics Co., Ltd. , a manufacturer of high-power semiconductor laser chips, announced the launch of a new 25W 9XXnm semiconductor laser chip, which is mainly used in fiber laser pumping, medical beauty, scientific research and other fields.

    The new 25W 9XXnm semiconductor laser chip model is RB-9XXA-190-25-4-SE, the luminescence strip width is 190μm, the cavity length is 4mm, the photoelectric conversion efficiency is 66%, the DOP is >96%, the service life can reach more than 30,000 hours. In addition, the chip also uses new epitaxial structure design and material epitaxy, leading cavity surface passivation technology, advanced non-pump window design and preparation technology and dry and wet corrosion combined with self-alignment technology, control the consistency of strip width, especially to ensure high yield under mass production, reduce the cost of laser chip.
