We present a Penning trap experiment for advanced studies with confined particles in extreme laser fields. Special interest lies in non-linear processes such as multiphoton ionization. Trap-specific manipulation techniques allow control over the stored particles' localization and spatial density. It is possible to select and prepare well-defined ion ensembles and to optimize the laser-particle interaction which is of special importance when laser foci are small. Non-destructive detection of reaction products with up to single-ion sensitivity supports advanced studies by maintaining the products for further studies at extended confinement times of minutes.
