Abstract:
An apparatus for adjusting a position of an optical component within a laser resonator, comprising:an electromechanical device including a drive element having a first direction of movement; an optical component of a laser resonator supported by a mechano-optical device, said mechano-optical device is coupled to the drive element for movement therewith, wherein the mechano-optical device has a second direction of movement different from the first direction of movement of the drive element; an optical component of a laser resonator supported by the mechano-optical device; wherein the electromechanical device adjusts the position of the optical component by moving the drive element and thereby adjusting the position of the mechano-optical device and the optical component; a controller for error correction of the position of the drive element, wherein the controller controls the electromechanical device; a position measuring device that measures a position of the drive element and forms a feedback loop that provides a signal indicative of the position of the drive element to the controller; and wherein the controller controls the electromechanical device to adjust the position of the drive element based on the signal provided by the position measuring device.
