Journal ArticleDOI
Femtosecond, picosecond and nanosecond laser ablation of solids
TL;DR: Theoretical models and qualitative explanations of experimental results are presented in this paper for femtosecond laser ablation of solid targets by 0.2-5000 ps Ti: Sapphire laser pulses.
Journal ArticleDOI
Ablation of metals by ultrashort laser pulses
Stefan Nolte,Carsten Momma,H. Jacobs,Andreas Tünnermann,Boris N. Chichkov,B. Wellegehausen,Herbert Welling +6 more
TL;DR: In this paper, the authors studied the ablation of metal targets by Ti:sapphire laser radiation and showed that the intensity depends logarithmically on the laser fluence.
Journal ArticleDOI
High-power fibre lasers
Cesar Jauregui,Jens Limpert,Jens Limpert,Jens Limpert,Andreas Tünnermann,Andreas Tünnermann,Andreas Tünnermann +6 more
TL;DR: An overview of the state of the art in the field can be found in this paper, where the authors discuss present challenges and the future outlook of high-power fiber laser applications.
Journal ArticleDOI
Asymmetric transmission of linearly polarized light at optical metamaterials.
Christoph Menzel,Christian Helgert,Carsten Rockstuhl,Ernst-Bernhard Kley,Andreas Tünnermann,Thomas Pertsch,Falk Lederer +6 more
TL;DR: A three-dimensional chiral optical metamaterial is experimentally demonstrated that exhibits an asymmetric transmission for forwardly and backwardly propagating linearly polarized light.
Journal ArticleDOI
Femtosecond fiber CPA system emitting 830 W average output power.
Tino Eidam,Stefan Hanf,Enrico Seise,T. V. Andersen,T. Gabler,Christian Wirth,Thomas Schreiber,Jens Limpert,Andreas Tünnermann +8 more
TL;DR: This Letter reports on the generation of 830 W compressed average power from a femtosecond fiber chirped pulse amplification (CPA) system and discusses further a scaling potential toward and beyond the kilowatt level by overcoming the current scaling limitations imposed by the transversal spatial hole burning.
