Abstract
Non-regenerative optical amplifier has a first optical amplifying medium and at least one second optical amplifying medium. The non-regenerative optical amplifier may be an ultrashort pulse amplifier. The material properties of the first amplifying medium differ at least partially from the material properties of the second amplifying medium. The emission spectra of the amplifying media overlap partially, and the amplifying media are solid-state bulk crystals.

Non-regenerative optical ultrashort pulse amplifier, comprising:
- a) a first optical gain medium;
- b) a second optical gain medium;
- c) the material properties of the first optical gain medium differ at least partially from the material properties of the second optical gain medium;
- d) the emission spectra of the first and second optical gain media partially overlap, the emission spectra of the first and second optical gain media are selected to overlap in such a way that a gain spectrum results which is spectrally expanded as compared to the individual emission spectra of the respective first and second optical gain medium;
- and
- e) the first and second optical gain media are formed by solid-state bulk crystals.
