  We provide a brief review of how phase space techniques are explored within
strong-field and attosecond science. This includes a broad overview of the
existing landscape, with focus on strong-field ionisation and rescattering,
high-order harmonic generation, stabilisation and free-electron lasers.
Furthermore, using our work on the subject, which deals with ionisation
dynamics in atoms and diatomic molecules as well as high-order harmonic
generation in inhomogeneous fields, we exemplify how such tools can be
employed. One may for instance determine qualitatively different phase space
dynamics, explore how bifurcations influence ionisation and high-harmonic
generation, establish for which regimes classical and quantum correspondence
works or fails, and what role different time scales play. Finally, we conclude
the review highlighting the importance of the tools available in quantum
optics, quantum information and physical chemistry to strong-field laser-matter
interaction.
