With innovative copper heat sinks, high-heat-dissipation hermetic packages give laser manufacturers a competitive edge by providing reliable, efficient, and flexible solutions.

SCHOTT’s new high-heat-dissipation TO-9 and SMD-based copper packages provide the thermal management necessary for high-power laser diodes to maintain beam performance and longevity.

Featuring copper heat sinks, these hermetic packaging components dissipate heat more efficiently than stainless steel or alloy headers.

The customizable components are ideal for laser systems used in industrial, medical, automotive, and consumer electronics applications.

SCHOTT, a leading developer and manufacturer of advanced electronic packaging solutions, announced the commercial availability of its next-generation high-heat-dissipation TO-9 and SMD-based copper packages. These cutting-edge components are designed to meet the growing thermal management challenges posed by high-power laser diodes.

SCHOTT will showcase these products during SPIE Photonics West from January 20 to 22, 2026 at Booth 1341 in the Moscone Center, San Francisco, California.

Solving high-power laser challenges
As laser power densities continue to increase, effective heat dissipation has become critical for maintaining laser beam performance and longevity. SCHOTT’s new hermetic packaging components with copper heat sinks deliver an exceptional thermal path, outperforming conventional stainless steel or alloy headers by dissipating heat significantly more efficiently.

The components are designed for laser system manufacturers in industrial, medical, automotive, and consumer electronics sectors, with typical applications including laser cutting and welding, aesthetic treatments and surgical procedures, head-up displays (HUDs), and advanced digital projection systems.

TO-9 platform: cost-effective, high-performance alternative to box packages
SCHOTT’s high-heat dissipation TO-9 transistor outline header offers a compelling replacement for traditional box packages. Its unique through-hole copper heat sink design delivers superior thermal performance, supporting excellent color and beam quality. SCHOTT's precision manufacturing ensures surface flatness, enabling stable laser output power and longevity — key requirements for high-power laser systems. These features make SCHOTT’s TO-9 an attractive option for manufacturers seeking to reduce costs without compromising performance.
