Behavior of threshold pump power of diode end-pumped solid-state lasers in critical cavity configurations

The influence of transverse mode locking in critical cavity configurations on the threshold pump power of diode end-pumped solid-state lasers was investigated both theoretically and experimentally for the large portion of the cavity stability region. An experimental study was performed for lasers based on Nd:YLF, Nd:YVO4, Nd:GdVO4 and Nd:KGW crystals.
