Inhomogeneous background fields convert Borel poles in the effective action to branch points and introduce new ones, allowing resurgent extrapolation to recover non-perturbative information from perturbative input more accurately than WKB or locally constant approximations.

Plasma transmission gratings with 10.2-micron period show 0.005 deg/nm angular dispersion in agreement with theory, supporting designs for damage-resistant laser pulse compressors reaching petawatt to exawatt powers.
Introductory lectures cover resurgent asymptotics using examples like the Airy function, nonlinear Stokes phenomenon, Heisenberg-Euler action, and resurgent continuation.
