Coherent is featuring its most comprehensive photonics portfolio at SPIE Photonics West 2026, demonstrating continuous-wave to ultrafast lasers, beam delivery systems and advanced materials tailored to key growth sectors. The company will present thermal management solutions such as sapphire and diamond heat spreaders alongside its latest visible lasers and specialty fiber assemblies. These innovations address demand in AI datacenters, semiconductor and display capital equipment, life sciences imaging and precision manufacturing. Live demonstrations include a thermo-electric generation system converting waste heat into usable power and a deep-UV film-cutting setup integrating a 266 nm picosecond laser. Participation in executive panels and technical sessions underlines Coherent’s leadership role in shaping next-generation data infrastructure and high-power fiber lasers.

In collaboration with Quside, Coherent achieved a milestone in hardware-based security by demonstrating a mass-manufacturable quantum entropy source using vertical-cavity surface-emitting lasers (VCSELs) on 6-inch wafers. For the first time, real-time verification of entropy from a single VCSEL delivers cryptographic-grade randomness suitable for secure key generation and quantum-safe architectures. This platform meets industry cost and reliability targets while enabling integration into mainstream processors, secure elements and hardware roots of trust. Investors may note that scaling fast, verifiable randomness into high-volume production positions Coherent and Quside to capture growing demand for entropy generation in data centers, defense systems and critical infrastructure.

Coherent’s newly launched bondable diamond solutions deliver ultra-high thermal conductivity heat spreaders engineered for direct die bonding with semiconductor materials including silicon, GaN and SiC. By controlling surface roughness, flatness and coatings, the technology reduces interfacial thermal resistance by up to 99% compared with conventional thermal interface materials. The company can process die sizes up to 100 mm square and customize metallic or fusion bonding approaches to meet diverse electronic and opto-electronic requirements. This vertically integrated capability—from diamond growth through precision finishing—enables large-scale production and positions Coherent to address the $2 billion thermal management market for high-power electronics and advanced photonic devices.
