ARRANGEMENT AND METHOD FOR CONVERTING ELECTROMAGNETIC RADIATION WITH A FIRST WAVELENGTH TO ELECTROMAGNETIC RADIATION WITH A SECOND WAVELENGTH

摘要

An arrangement (100) for converting first electromagnetic radiation with a first wavelength to second electromagnetic radiation with a second, longer wavelength. The arrangement comprises a laser source device (102) and a wavelength converter device (104). The laser source device comprises a laser apparatus (116) which is a semiconductor laser that is configured to produce first light with a first wavelength in the near-infrared range, the first wavelength being between 750 nm and 850 nm. The wavelength converter device is configured to receive said first light as an input and produce second light with a second wavelength in the mid-infrared range as an output.
