When linear and nonlinear chirp are optimally compensated for, corresponding to the quadratic, cubic, and quartic phases of -- 400 fs2, 1100 fs3, and 2000 fs4 at the center wavelength 780 nm on the SLM, a stronger chirped white light continuum (WLC) pulse with a spectral bandwidth of 570-970 nm is compressed to the sub-6-fs regime.IEEE: Institute of Electrical and Electronics EngineersJournal Articleapplication/pdfhttp://hdl.handle.net/2115/45329https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/45329/1/PTL12-11_1540-1542.pdf1041-1135IEEE Photonics Technology Letters1211154015422000-11enginfo:doi/10.1109/68.887740© 2000 IEEE.
