We also confirmed up to the 95-μJ output from the amplifier when seed pulses were not pre-compensated for. Furthermore, we confirmed that the broadband pump pulses brought in the broader gain bandwidth (from 520 to 1080 nm) than numerical estimation based on CW-pump approximation. To the best of our knowledge, this is the system with the broadest gain bandwidth.Optical Society of AmericaJournal Articleapplication/pdfhttp://hdl.handle.net/2115/45303https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/45303/1/OE16-22_18345-18353.pdf1094-4087Optics Express162218345183532008-10-27enginfo:doi/10.1364/OE.16.018345© 2008 Optical Society of Americapublisher
