  Fabry\, 2 Av. Augustin Fresnel\, 91127 Palaiseau\, France\nWe present a s
 pectral phase-only shaping technique allowing to generate arbitrary tempor
 al shapes and demonstrate its use for ultrafast ytterbium-based laser sour
 ces. This technique is based on the introduction of a nonlinear chirp that
  is determined solely by the input spectral intensity and the target tempo
 ral intensity\, as shown in Fig 1.\n\nFigure 1: Top - spectrum (black) and
  applied delay (dashed green) via spectral phase control. Bottom - Resulti
 ng temporal profile (green) and target temporal profile (black).\nWe descr
 ibe its working principle and experimentally demonstrate the generation of
  triangle shaped pulses at the output of a laser source\, which delivers 1
 50 µJ\, sub-200 fs pulses at 150 kHz. These pulses are then passed throug
 h a nonlinear multipass cell to observe wavelength shifting via self-phase
  modulation. A spectral tunability of 28 nm is achieved around the input c
 entral wavelength of 1034 nm.\n\nhttps://indico.gsi.de/event/25601/
