Zusammenfassung:	We report on ultrafast photoindued charge density wave (CDW) dynamics in the transition-metal dichalcogenide 4H_b-TaSe₂, studied with ultrafast electron diffraction. Fluence dependence of the lattice superstructure suppression show a phase transition from the commensurate to the incommensurate phase of 4H_b-TaSe₂. Unusually long recovery times of perturbed charge density waves indicate th importance of a coupling between the two dimensional CDWs.
