High-power blue laser technology developer Nuburu (Centennial, CO) has been awarded U.S. Patent No. 10,971,896 by the U.S. Patent Office. This new patent covers spatial, polarization, and wavelength combination of blue laser diodes to make a high-power, high-brightness blue laser diode system, which enables significant gains in speed and quality for metal processing.
This additional U.S. patent enriches Nuburu’s expansive IP portfolio that has grown substantially over the last few months. In 2021 thus far, the company has added nine patents across 3D printing and material processing. Its foundational patent, “3D printing Devices and Methods” (PCT/US14/35928), was awarded in 16 countries with several other applications and continuations pending around the world, including with the U.S. Patent Office (2016/0067780).
Nuburu’s blue lasers have uses in materials processing applications across e-mobility and automotive, energy storage, aerospace, and additive manufacturing. In many industrial applications, critical materials such as copper, stainless steel, and aluminum do not absorb much of the infrared wavelengths transmitted by traditional industrial lasers, which leads to lower quality joints.
Nuburu’s industrial blue lasers are said to produce defect-free welds up to 10X faster than the traditional approaches, and can also address complex situations such as the joining of dissimilar metals.
