What is the Coherent Founding Story?

Founding Story of Coherent traces back to II-VI Incorporated, established on June 22, 1971 in Saxonburg, Pennsylvania, by engineer Carl J. Johnson and business leader Francis J. Kramer; the company focused on high-performance II-VI compound materials for infrared optics and CO2 lasers. Decades later II-VI acquired Coherent, Inc. and adopted the Coherent name to reflect a full photonics systems strategy.

Founding Story: From Materials to Full Photonics

II-VI began as a specialty materials and precision optics supplier in 1971; the 2022 acquisition of Coherent expanded the firm into complete photonics systems and solutions.

  • Founded June 22, 1971 in Saxonburg, PA by Carl J. Johnson and Francis J. Kramer
  • Initial focus on II-VI compound materials such as zinc selenide (ZnSe) for infrared optics and CO2 lasers
  • Bootstrapped early growth with defense and industrial customer-funded development during 1970s U.S. manufacturing expansion
  • II-VI closed acquisition of Coherent, Inc. on July 1, 2022 and adopted the Coherent name

The II-VI name referenced Group II and Group VI elements, signaling a materials-science foundation; first products included infrared optical components and windows for CO2 laser systems and thermal imaging, addressing defense and industrial markets. Early revenue growth was supported by government and industrial contracts typical of Cold War R&D spending in the 1970s.

Coherent, Inc., originally founded in 1966 in Palo Alto by physicists including James Hobart, built a reputation for commercial gas and solid-state lasers; combining II-VI and Coherent created a diversified photonics leader with combined 2023 pro forma annual revenue reported by the merged company near $4.3 billion (company disclosures for FY2023 pro forma results). For investors seeking more context, see Growth Strategy of Coherent.

Key milestones in the combined Coherent company timeline include: initial II-VI product launches in the 1970s, multi-decade expansion into precision optics and components, public listings and capital raises across the 1980s–2010s, and the strategic merger on July 1, 2022 that created a broader photonics portfolio spanning materials, components, lasers, and systems—shaping the Coherent company history and modern positioning in the laser and photonics industry.
