Abstract

<jats:p>A time-dependent and three-dimensional dye laser amplifier simulation is presented. Its amplified spontaneous emission (ASE) is simulated by distinguishing the propagating directions of the angularly divided ASE, which makes it possible to simulate both the laser and ASE. Strong generation of the ASE is seen from the part of the excited volume where there is no input signal, indicating that ASE greatly depends on the input-beam geometrical profile, as well as its temporal matching with the pumping beam.</jats:p>
