摘要：
For optical data storage applications, for example, for holographic storage applications, a radiation beam (12) with a flat intensity profile is needed. The radiation source device (1) of the invention comprises a beam shaper element (5) and a collimating element (7) between a semiconductor laser (3) and an output coupler (9) and provides such a radiation beam (12) with an increased efficiency. An external resonator is thereby provided. Further, a relatively fast tuning of the wavelength of the output radiation beam (12) can be provided.
