摘要: The present invention relates to a system and a method for processing electromagnetic radiation. In particular, the present invention relates to conversion of light, such as light (28) comprising image information (34), from one wavelength interval to another wavelength interval. More in particular, the present invention relates to wavelength conversion of incident light (28) by means of optical mixing with a laser beam in a non-linear crystal (14). The method according to the present invention comprises receiving incoming electromagnetic radiation (28) and a laser beam (12) in a non-linear crystal, setting a plurality of phase match conditions within the non-linear crystal (14), obtaining a plurality of images of the processed electromagnetic radiation (30), and providing a first combined image (42) comprising a first part of a first image and comprising a second part of a second image. The wavelength conversion is realized in an intra-cavity arrangement by for example sum-frequency generation between the intra-cavity laser light (12) and the in-coupled radiation (28).
