Phys. Rev. A 67, 051801(R) (2003) [4 pages]Continuously tunable high-order harmonics from atoms in an intense femtosecond laser field
Through the control of laser energy and chirp, continuous wavelength tuning of high-order harmonics was achieved without sacrificing spectral sharpness. This process was implemented after the amplification stage in a chirped-pulse amplification Ti:sapphire laser, without changing laser spectrum. It opens a new pathway for the realization of a continuously tunable, coherent, femtosecond x-ray source, i.e., a tabletop synchrotron. © 2003 The American Physical Society URL:
