In the present work we report the synthesis of poly((4-hydroxy-3-(pyridin-3-yldiazenyl)phenethyl)methacrylamide-co-dimethylacrylamide) and its reversible optical and complex-forming properties due to copper and cyclodextrin (CD) interactions. Color c

Publikováno v: Scopus-Elsevier

· Background: Recently, laser systems have become available which generate ultrashort laser pulses with a duration of 100–200 femtoseconds (fs). By generating micro-plasmas inside the corneal stroma with fs pulses, it is possible to achieve a cutt

Chemical and physical side effects at application of ultrashort laser pulses for intrastromal refractive surgery

Autor: Stephan Barcikowski, Gero Maatz, Carsten Fallnich, Alexander Heisterkamp, Herbert Welling, Holger Lubatschowski, Wolfgang Ertmer

Focusing femtosecond (fs) laser pulses into transparent media, such as corneal tissue, leads to optical breakdown, generation of a micro-plasma and, thus, a cutting effect inside the tissue - provided the intensity at the focus exceeds a threshold wh
