High-efficiency generation of polygonal GPSTOV pulses with tunable topological charge

Caption

Fig. 2 | Generation of generalized perfect spatiotemporal optical vortice (GPSTOV) pulses with polygonal shapes. (a) Experimental results of triangular, square, and pentagonal GPSTOV pulses with a topological charge of ℓ = 2. The upper and lower panels show the spatiotemporal intensity and phase distributions in the x-t plane, respectively. (b) Same as (a), but with a topological charge of ℓ = 6. (c, d) Comparison of the 1D intensity profiles extracted along the dotted lines indicated in (a, b), respectively.
