Spatial radiation intensity distribution of linear diode arrays and calculation of inversion in fibre-coupled end-pumped solid-state lasers

The radiation intensity distribution of linear diode arrays used for longitudinal pumping fibre-coupled solid-state lasers is studied experimentally and theoretically. A simple model describing the propagation of radiation is proposed which allows the calculation of the inversion population distribu...

Zusammenfassung:The radiation intensity distribution of linear diode arrays used for longitudinal pumping fibre-coupled solid-state lasers is studied experimentally and theoretically. A simple model describing the propagation of radiation is proposed which allows the calculation of the inversion population distribution in an active element. The radiation intensity distributions are calculated in cross sections for different angular distributions at the fibre output. (lasers)
