Adalbert Ding Berichter: Dr.-Ing. Hans Joachim Eichler Vorsitzender: Prof. Dr. Erwin Sedlmayr To the souls of my parents I present this work… They wanted to be happy to see this work finished… But they died before it… I think they are now happy to see it finished… I also present this work to my home country Egypt and to Germany… Yasser Abstract Two new solar directly-pumped solid state laser systems were developed to avoid the disadvantages of the previously developed system. Using the advantages of the Fresnel lenses, a small solar directly-pumped laser system was developed.
