摘要：A method for the self-calibration of a tunable, diode pumped solid state laser inwhich the frequency or the wavelength of the laser radiation of the fundamentalfrequency and/or doubled frequency is changed by of changing the optical cavity lengthby means of a piezo-actuator or Brewster window over the total amplification bandwidthof the laser-active material. According to the method, the performance curves during thetuning of an etalon or corresponding optical elements arranged in the cavity arerecorded and stored and a tuning function for the respective optical element or opticalelements is generated (derived) from these curves by a microcontroller or computer. Anoptimum working point for the optical element or optical elements for maximumsuppression of side modes is adjusted by a digital or analog regulator with the help of alearning curve (learning characteristic). In the solid state laser, an etalon is provided insidethe cavity for changing (expanding) the tuning range and for determining the outputpower of the laser, wherein the etalon is rotatable or swivelable about an axis of rotationwhich extends at right angles to the optical axis of the laser or so as to be inclinedrelative to the latter by a small angle.
