Proceedings ArticleDOI
Wavelength Dependence of Maximal Diffraction-Limited Output Power of Fiber Lasers
TL;DR: In this article, the influence of different operation wavelengths on the heat load in a fiber-laser was studied and the authors provided guidelines to maximize the diffraction-limited output power.
Book ChapterDOI

TL;DR: In this paper, an ytterbium-doped fiber CPA system delivering millijoule energy 800fs pulses at high repetition rates and average powers exceeding 100 W was presented.
Proceedings ArticleDOI
Influence of pulse duration on the hole formation during short and ultrashort pulse laser deep drilling
TL;DR: In this article, the authors investigated the influence of the pulse duration on the laser drilling process in the femtosecond, picosecond and nanosecond regime by in-situ imaging of the hole formation in silicon for pulse energies from 25 μJ to 500 μJ.
Journal ArticleDOI
Low temperature deposition of indium tin oxide films by plasma ion-assisted evaporation
TL;DR: In this article, an improved coating process for ITO based on plasma ion-assisted evaporation at a substrate temperature below 100 °C, which is suitable for organic substrates, is described.
Journal ArticleDOI
80 kHz repetition rate high power fiber amplifier flat-top pulse pumped OPCPA based on BIB_3O_6
TL;DR: High peak power optical parametric chirped pulse amplifier seeded by a cavity dumped Ti:Sapphire oscillator and broadband amplification around 800 nm central wavelength is demonstrated in BIB(3)O(6) (BIBO) crystals.
