Ultra short pulse pump source for generating a plurality of pump pulses

摘要

The present invention relates to an ultra short pulse pump source (1) with at least one seed pulse source (2) for generating a seed pulse laser beam (3) at least one laser gain medium (4) for the amplification of the seed pulse laser beam, as well as a beam guide optical system (5) for guiding the seed pulse laser beam (3) by means of the laser gain medium (4). The ultra short pulse pump source is characterized in that the ultra short pulse pump source (1) at least one second seed pulse source (6) for generating a to the first seed pulse laser beam (3) synchronous second seed pulse laser beam (7), and further comprising a beam combiner (8) for the spatial superposition of the first and second seed pulse laser beam (3, 7) in the laser gain medium (4) comprises.
