  We demonstrate that light-induced heat pulses of different duration and
energy can write skyrmions in a broad range of temperatures and magnetic field
in FeGe. Using a combination of camera-rate and pump-probe cryo-Lorentz
Transmission Electron Microscopy, we directly resolve the spatio-temporal
evolution of the magnetization ensuing optical excitation. The skyrmion lattice
was found to maintain its structural properties during the laser-induced
demagnetization, and its recovery to the initial state happened in the
sub-{\mu}s to {\mu}s range, depending on the cooling rate of the system.
