JK Lasers was a global laser manufacturer based in Rugby, Warwickshire, England. Established by Ron Burbeck and Dr Jim Wright MBE in 1972, the company first launched a range of pulsed lasers using ruby, YAG and glass laser rods. This was followed by the MS-Series of Nd:YAG laser systems, designed for industrial welding, cutting and drilling applications. In April 2015 GSI sold its JK Lasers subsidiary to SPI Lasers, part of the Trumpf group. All products were rebranded with the SPI logo, essentially ending the JK brand.
