New transient effects in pulsed thermal blooming

Open Access Open Access

Abstract

Pulsed thermal blooming typically develops rather slowly after a beam is turned on at time t = 0. This result may be obtained by examining the differential equation for the variation of the refractive index with time after turn-on. This paper examines the transient effects which may be introduced at the edges of the aperture. These effects give rise to faster local onset of blooming and discontinuities and may influence beam Instabilities. (12 min)
