Abstract
A device for moving a nonlinear crystal or a saturable absorber in two dimensions includes a first and a second piezo unit, each having a corresponding carrier, piezo driver, and carriage moveable by the piezo driver at incremental steps along a linear path with respect to the carrier between a first and a second end location, in which the linear paths of the first piezo unit and the second piezo unit are orthogonal. The nonlinear crystal/saturable absorber is fastenable on the carriage of the first piezo unit and the carrier of the first piezo unit is fastened on the carriage of the second piezo unit. The device further includes stops that define the carriage end locations, an end location detection configured to detect the carriages at their respective end locations, and a counting unit configured to count the steps covered during the moving of the carriage.
