Festkoerperlaser mit phasenkonjugierenden Spiegeln. Anlage zum Forschungsbericht - Fiberbuendel-Laser Abschlussbericht

1. Goals of the project - fiber-bundle-laser (FBL) with average power of 100 W, pulse energy 1-2 J, and simultaneous emission at two wavelengths - have been reached with optimization of the fiber material, the number of fibers, resonator and technology of the FBL. 2. Cultivation of highly doped multi component glasses for fiber laser applications. 3. Melting of the bundle end-sections by the 'glass-solder' method. 4. Additional results: passive Q-switching of the FBL, development of adapted micro-mirror arrays. 5. The possibility of scaling could be demonstrated and necessary conditions could be defined for the improvement of the beam quality (promising results with phase conjugation) and the total efficiency.
