Abstract
A method for adjusting an intensity of a light beam in an optical arrangement includes passing the light beam through an acousto-optical tunable filter (AOTF). The intensity of the light beam is adjusted as a function of frequency and/or amplitude of a sound wave with which the AOTF is operated. The amplitude of the sound wave at a specified sound wave frequency is selected such that the amplitude is larger than would be required to achieve a first maximum diffraction efficiency for a specified wavelength or for a specified wavelength spectrum of the light beam. The amplitude of the sound wave is also selected such that a value of an integral of a product of the transmission function of the AOTF and the wavelength spectrum of the light beam is larger than at a value of the amplitude to be selected to achieve the first maximum.
