Profile

The Laser Development Department focuses on the design, construction and characterization of diode-pumped solid-state and fiber lasers. Beam sources and fiber components for highly specialized applications and for industry are important research and development fields.

These include research missions in space: LZH lasers will be flying to the Mars soon and withstand harsh environmental conditions. Moreover, the lasers of the LZH scientists are used to detect gravitational waves or to explore the deep sea.

The work areas of the department range from industry-oriented applications to fundamental research.
