On the relation between periodically deflected and transverse mode-locked laser beams
Michael Zwilich, Jan Wichmann, Carsten Fallnich
Transverse mode-locked (TML) beams exhibit high-speed beam scanning, which motivates a comparison with established beam deflection technologies, such as galvanometer and voice coil…

Hermite-Gaussian multi-mode excitation in spatial gain shaping approaches for laser resonators
Michael Zwilich, Carsten Fallnich
This study explores the excitation of transverse laser modes through spatial gain shaping, while focusing on the boundary between selective single-mode and multi-mode lasing. By de…

Spatiotemporal wavevector dynamics of transverse mode-locked beams
Jan Wichmann, Michael Zwilich, Carsten Fallnich
The phase-locking of transverse higher-order resonator modes results in a beam with rapidly oscillating spatial intensity profile. To complete the description of such transverse mo…
