    • note
    • The TA spectrum show in Figure 1 was measured in three seperate experiments: region 1 (450-720 nm), region 2 (720-850 nm), and region 3 (850-1300 nm). In recording region 2, a mirror that partially transmits the 795 nm fundamental light in the continuum prevents saturation of the detector while allowing the use of the adjacent continuum on both sides of the fundamental wavelength.
