Compact 20-pass thin-disk amplifier insensitive to thermal lensing
M. Zeyen, A. Antognini, K. Kirch +8
We present a multi-pass amplifier which passively compensates for distortions of the spherical phase front occurring in the active medium. The design is based on the Fourier transf…
Passive alignment stability and auto-alignment of multipass amplifiers based on Fourier transforms
Karsten Schuhmann, Klaus Kirch, Andreas Knecht +8
The stability properties of Fourier-based multipass amplifier to misalignments (tilts) of its optical components has been investigated. For this purpose, a method to quantify the s…
Multi-pass amplifiers with self-compensation of the thermal lens
Karsten Schuhmann, Klaus Kirch, Miroslaw Marszalek +7
We present a novel architecture for a multi-pass amplifier based on a succession of optical Fourier transforms and short propagations that shows a superior stability for variations…
