Abstract
The invention makes it possible to adjust the light intensity of a laser scanning microscope laser beam in an economical manner and with high accuracy. A separate acousto-optic component can be omitted in that a light modulation section such as an electroabsorption modulator (EAM) or a semiconductor amplifier (SOA) is arranged directly at the laser diode, advisably at one of its front sides. It is nevertheless possible to control the light intensity economically and with high accuracy because the important parameters of the laser beam remain unchanged when the optical output power is changed by the light modulation section. The light modulation section is preferably formed integral with the laser diode in at least one material layer.
