Coherent was founded as II-VI Incorporated in 1971 by Carl Johnson and James Hawkey.[5][6] The name "II-VI" is a reference to the groups II and VI in the periodic table, since the company started its business by producing cadmium telluride (cadmium belongs to group II and tellurium belongs to group VI).[7] The company's first products included lenses, windows, and mirrors for CO2 lasers.[5]

In the 1990s, the company began to grow both on its own and through acquisitions.[5] It purchased Litton Systems' silicon carbide group from Northrop Grumman in the 1990s,[5] Virgo Optics in 1995,[8] and Lightning Optical Corporation in 1996,[8] among others. The combination of Virgo and Lightning created II-VI's VLOC division for developing one-micron solid-state lasers.[8] Acquisitions in the 2000s have included Laser Power Optics in 2000; Marlow Industries in 2004;[9] HIGHYAG (75% in 2007[10] and the remaining 25% in 2013); Photop Technologies in 2010;[11] Oclaro's Santa Rosa, California, optics coating facility in 2012; Anadigics and EpiWorks in 2016;[12] and Integrated Photonics in 2017.[13][8] The acquisition of Avalon Photonics, Anadigics, and EpiWorks allowed II-VI to increase its production of vertical-cavity surface-emitting lasers (VCSELs),[8] important to 3D sensing technology; and the acquisition of Finisar Corporation in 2019 brought to II-VI Finisar's high volume 3DS VCSELs indium phosphide (InP) platform and its experience in integrating InP lasers with optics and electronics in transceivers.[8] Acquisitions of INNOViON, Ascatron, and some of GE's patents have expanded its business in silicon carbide substrates.[8] In 2022, II-VI acquired laser manufacturer Coherent, Inc..[14] and took the name Coherent Corp.

The Saxonburg headquarters site was once the property of KDKA, the world's first commercially licensed radio station, and some of the original structures are still there.[20] In the 1940s, the site was expanded by the Carnegie Institute of Technology and the U.S. Nuclear Regulatory Commission to become a 400 MeV synchrocyclotron research facility.[21] II-VI acquired the property around 1978 and has further expanded the facility over the years.[22]
