      abstract     = {Precise control of the temporal profile of laser pulses is
                      critical for many scientific and industrial applications.
                      Achieving this via spectral shaping is particularly
                      challenging in complex systems due to nonlinear effects,
                      input fluctuations, and hardware imperfections. Conventional
                      approaches - such as manual iterative tuning, precomputed
                      spectral settings, or evolutionary optimization - are often
                      insufficient or scale poorly with system complexity. We
                      introduce a differentiable physics-based framework for
                      spectral pulse shaping that embeds a physical model of the
                      laser within a gradient-based optimization loop. This
                      approach enables rapid system identification and control,
                      accurately capturing complex laser dynamics while optimizing
                      control inputs to achieve target temporal pulse shapes. We
                      demonstrate the method by shaping near-infrared pulses as a
                      proof of concept for photoinjector laser systems,
                      highlighting its generality and potential for
                      high-dimensional control of complex physical systems.},
