About

Holger Kern is a laser physicist and optical engineer whose research has focused on advancing the power and brightness capabilities of diode laser systems. Working at the forefront of high-power photonics, Kern has made significant contributions to beam combining techniques that address one of the field's most persistent challenges: scaling output power while preserving beam quality. His work at DirectPhotonics has been instrumental in developing and refining approaches such as optical stacking and dense spectral combining (DSC), innovations that are helping diode lasers compete with established solid-state technologies like disk and fiber lasers. Kern's 2015 paper on beam combining techniques has garnered 11 citations, reflecting meaningful engagement from the research community, while his 2014 study demonstrating kilowatt-level output power from high-brightness direct diode lasers further established his credentials in this competitive field. Together, these publications underscore his practical, application-driven approach to photonics research. For students and researchers exploring high-power laser development, Kern's work offers valuable insight into the engineering pathways that are enabling next-generation diode laser systems to meet the demanding requirements of industrial and scientific applications.
