“…It is possible to compensate the temporal chirp in vortex pulses using normal dispersion compensation techniques. Such techniques to compensate dispersion includes prisms [33], semiconductor saturable absorber mirrors SESAMs, among others but specifically multilayer interference coatings, such as chirped mirrors [34] (CMs) are a compact solution with a much larger bandwidth and custom compensation of high order dispersion [35]. In addition computer optimized designs of multilayer structures have been demonstrated [36].…”

A new device concept -the reflective spiral phase converter -is presented. The converter can be used for generation of ultrashort optical vortices and takes advantage of spiral phase plate to impose the vortex phase, and of a multilayer structure to compensate the dispersion acquired by incident pulse. We use (3+1)D numerical analysis of the spatio-spectrotemporal properties of ultrashort vortex pulses to quantify the effects of chromatic dispersion and propagation geometry, and characterize the efficiency of the device by checking the purity of the modes generated. Results of case studies in UV-VIS-NIR spectral ranges are presented. The proposed device allows to surpass the limitations of bandwidth from standard SPPs while keeping the pulse width and shape as undistorted as possible so it can widely be used for generation of ultrashort optical vortices.

“…To numerically determine the GDD and third-order dispersion (TOD) of our BPC, we used a toolbox. 14,15 It determines GDD and TOD for some central wavelength λ 0 based on a prism compressor's geometry (Fig. 5), involving quantities such as incidence angle ϑ 0 , prism apex angle α, distance from apex to ray 1 (l 1 ), and distance from apex to ray 2 (l 2 ).…”

A novel characterization method to measure the pulse duration of ultrafast near-IR pulses is introduced, which uses simple tabletop optics, is relatively inexpensive, and is expected to work in a broad wavelength range. Our diagnostic tool quantitatively characterizes the laser pulse duration of any near-IR wavelength assuming a Gaussian pulse shape with a linear chirp. We negatively prechirp near-IR pulses with a home-built broadband pulse compressor (BPC) and send this prechirped beam through a cell filled with a low-molar solution of a fluorescent dye in a liquid. After two-photon absorption, this dye fluoresces in the visible, and we record this visible signal as a function of the propagation distance in the liquid cell. We calibrate the group velocity dispersion (GVD) of our home-built BPC device against the known GVD of the compressor of our 800 nm laser and confirm this value using geometric considerations. Now knowing the GVD of BPC and the recorded visible signal for various amounts of negative chirp, let us extract the smallest pulse duration of the near-IR pulse from this visible signal. As a useful corollary, our analysis also enables the direct measurement of the GVD for liquids and the indirect measurement of the absorption coefficient for liquids in the near-IR range, in contrast to indirect GVD measurements that rely on methods such as the double derivative of the refractive index.
