Porphyrins are a ubiquitous large class of naturally occurring macrocyclic compounds with many significant biological representatives comprising heme and chlorophyll. Some novel adaptable methods for the synthesis of free-based porphyrins as promising sensitizers for the use in photo-dynamic therapy by the virtue of their known tumor affinity, low dark cytotoxicity, and easy synthesis in good t...

We investigate high brightness pumping of a multi-kW Yb fiber amplifier in a bi-directional pumping configuration. Each pump outputs 2 kW in a 200 μm, 0.2 NA multi-mode fiber. Gold-coated specialty gain fibers, with 17 m MFD and 5-dB/meter pump absorption, have been developed. The maximum fiber amplifier output power is 3.1 kW, limited by multi-mode instability, with 90% O-O efficiency 12 GHz ...

The present PhD thesis focuses on the development of biocompatible high-precision scaffolds with complex architectures for applications in the field of biomaterials and photonics. Self-assembled peptide fibrils were designed in order to be used as novel materials. Their positioning and integration into devices fabricated with femtosecond laser technologies, was further examined. 3D scaffolds wi...
