摘要 |
The invention relates to a device for generating electromagnetic radiation, comprising a pump light source (1), which emits a substantially monochromatic excitation radiation (5) at a first wavelength, and an optical waveguide (2), which generates frequency-converted radiation (6, 7) at a second and a third wavelength from the excitation radiation (5) of the pump light source (1) by means of degenerate four-wave mixing. The problem of the invention is producing a device which ensures an improved pulse shape and conversion efficiency. According to the invention a filter element (3) is provided, which attenuates the radiation (6, 7) at the second or third wavelength. |
