Abstract
The invention describes a method of heating a preform () characterized by a radius (R), a material thickness (t), and a material absorption spectrum, which method comprises the steps of selecting, depending on a desired temperature profile, a desired effective absorption coefficient for the preform () on the basis of the preform radius (R) and material thickness (t); generating a laser radiation beam (L) comprising radiation with a wavelength spectrum compiled on the basis of absorption coefficients of the absorption spectrum to satisfy the effective absorption coefficient and directing the laser radiation beam (L) at the preform () to heat the preform (). The invention further describes a driving arrangement () for controlling a laser radiation generating unit () of a preform heating system (), a preform heating system (), and a computer program.
