An illumination apparatus includes a semiconductor laser device to generate a plurality of laser beams, a light wavelength conversion element configured to convert at least a portion of the light of the laser beams into light having a different wavelength, and an optical unit configured to direct the laser beams onto a surface of the light wavelength conversion element. The optical unit includes a mirror element able to be panned about an axis and is configured to guide the laser beams over at least one surface section of the surface of the at least one light wavelength conversion element. The optical unit includes a structure configured to adjust a divergence or expansion of the laser beams along at least one of a slow axis or a fast axis of the laser beams on the surface section of the surface of the at least one light wavelength conversion element.

Illumination apparatus

A device and a method is proposed for writing on imaging material ( ) with a radiation source ( ) producing an electromagnetic radiation having a wavelength suitable for recording image information on the imaging material ( ). The radiation produced by the radiation source ( ) can be modulated with a waveguide which is integrated in a substrate material ( ) and operates as a modulator ( ). A modulation signal containing the image information can be received at an input ( ) of the modulator ( ). According to the invention, a compensator ( ) compensates a modulation error which occurs during modulation of the radiation.
