英文摘要	The invention describes a laser arrangement (100) comprising at least one VCSEL array comprising two, three, four or more VCSELs (130) arranged on a common semiconductor substrate (101), wherein the laser arrangement (100) further comprises at least one optical structure (140) and a diffusor structure (145), wherein the optical structure (140) is arranged to reduce a divergence angle of laser light (10) emitted by each VCSEL (130) to a section (147) of the diffusor structure (145) assigned to the respective VCSEL (130), wherein the diffusor structure (145) is arranged to transform the laser light received from the optical structure (140) to transformed laser light (150) such that a continuous illumination pattern (20) can be provided in a reference plane in a defined field-of-view, wherein the diffusor structure (145) is arranged to increase a size of the illumination pattern (20) in comparison to an untransformed illumination pattern which can be provided without the diffusor structure (145). The invention further describes a lighting device comprising such a laser arrangement, a time-of-flight camera (200) comprising such a lighting device and a method of manufacturing the laser arrangement (100).
