As a partner on developing laser glass components, SCHOTT Advanced Optiocs is involved in large projects such as those that Lawrence Livermore National Laboratory (on the left) is working on or in planning petawatt lasers at the European level (on the right).

In addition to production in Mainz, Germany, SCHOTT Advanced Optics manufactures the majority of its laser glasses in Duryea, Pennsylvania. The Research & Development center for these products is also based there. Distinguished glass experts, such as Dr. Joseph S. Hayden, who has made a significant contribution to SCHOTT’s leading market position, also research glass and its properties in Duryea. Hayden, an internationally renowned laser glass expert, joined SCHOTT in 1985, where his work on compositional modifications and the identification of special post-processing treatments was crucial in expanding the operational window for laser glasses.
But SCHOTT’s success in the field has also been influenced by other factors, as Hayden himself acknowledges. Now a Research Fellow in Duryea, he was in July 2014 honored with the Stookey Award of the American Ceramic Society (ACerS) for lifetime contributions in the field of glass and glass-ceramics. In his Lecture of Discovery presentation, Hayden paid tribute ”to the many scientists, engineers and technicians involved in these collaborations who have individually or collectively contributed to the progress in the field.” Of particular note was the frequent technical and financial support of John H. Campbell and other researchers at Lawrence Livermore National Laboratory (LLNL).
Laser glass expert Dr. Simi George: ”We can thank the many international ventures on large-scale laser projects around the world for providing the necessary drive to further develop laser glass materials.” In most of them, SCHOTT is involved as a partner and has developed the required laser glass components, e. g. at the LLNL and the French Commissariat à l'Énergie Atomique (CEA). ”SCHOTT is also actively involved in the planning of projects exceeding the PW (petawatt) level,” continues George, ”but here we are not simply faced with the challenge of just ’bigger and better’ glass. Instead the laser glass needs to provide sufficient gain width for the incredibly short pulses – we are going to be cooking up new glasses!”
