5th Otto Schott Research Award

He conducted numerous projects that resulted in a basic understanding of the properties of glass, especially in the area of multi-component phosphate glasses, and advanced the level of scientific knowledge with respect to critical issues.

He made pioneering contributions towards glass, especially in the areas of laser glass and optical fiber glasses and devices.

His far-reaching vision and contributions in the first realizing laser action in glasses leads to his discovery of both neodymium and erbium doped laser glasses and his development of the first fiber amplifier.
