Recordings of near-field patterns with an integration time as small as 1 ns allow us to follow the evolution of the transverse intensity profile along the output pulse of the laser.engDynamic transition from modelike patterns to turbulentlike patterns in a broad-area Nd:YAG laserjournal articlehttps://doi.org/10.1364/OL.31.001067https://www.osapublishing.org/ol/abstract.cfm?uri=ol-31-8-1067#Abstractrestricted access537.8535.374LasersNeodymiumNonlinear opticsNd:YAG lasersSurface emitting lasersFresnel numberElectromagnetismoÓptica (Física)Láseres2202 Electromagnetismo2209.19 Óptica Física2209.10 Láseres
