dc.description.abstract | We present an in situ beam characterization technique to analyze
femtosecond optical beams in a folded version of a 2f-2f setup. This
technique makes use of a two-dimensional spatial light modulator (SLM) to
holographically redirect radiation between different diffraction orders. This
manipulation of light between diffraction orders is carried out locally within
the beam. Because SLMs can withstand intensities of up to I~10^11 W/cm,
this makes them suitable for amplified femtosecond radiation. The flexibility of the SLM was demonstrated by producing a diverse assortment of "soft apertures" that are mechanically difficult or impossible to
reproduce. We test our method by holographically knife-edging and
tomographically reconstructing both continuous wave and broadband
radiation in transverse optical modes. | en |
