Journal ArticleDOI
Scalable concept for diode-pumped high-power solid-state lasers
TL;DR: In this article, a very thin laser crystal disc with one face mounted on a heat sink is proposed for diode-pumped high-power solid-state laser systems, which allows very high pump power densities without high temperature rises within the crystal and leads to an almost homogeneous and one-dimensional heat flux perpendicular to the surface.

Laser amplifier system
TL;DR: In this article, the authors proposed a radiation field guiding optics which enables the amplifier radiation field to enter the solid body in the form of a number of incident branches with locally different trajectories.
Journal ArticleDOI
High-resolution knife-edge laser beam profiling
TL;DR: In this paper, a knife-edge method for profiling focused and unfocused laser beams with a high spatial resolution is presented, which is equivalent to the slit method but with a variable slit width also on a sub-μm scale.
Proceedings ArticleDOI
Diode-Pumped High-Power Solid-State Laser: Concept and First Results with Yb:YAG
TL;DR: In this paper, a concept for a multi-100 W Yb:YAG laser, utilizing very thin crystal discs to allow high pump-power densities without efficiency reduction or thermal distortion, is presented.
Proceedings ArticleDOI
Efficient high-power-diode-pumped thin-disk Yb:YAG-laser
TL;DR: In this article, a diode-pumped high-power operation of quasi-three-level laser with high beam quality is presented. Butler et al. used a very thin crystal disk with one face mounted on a heat sink together with the low heat generation of Yb:YAG (5 kW/cm2) for efficient operation without strong thermal degradation or optical distortion.
