Abstract
A laser oscillator and a method for controlling the laser oscillator. The laser oscillator has a control unit and a laser unit. The control unit applies control signals to the laser unit to control the power and wavelength of a laser light produced by the laser unit. The control unit has a calculation device for calculating values for the controls signals which will cause the power and wavelength of the laser light to be at predetermined values on the basis of the predetermined values and a truncated power series relating values for the control signals to values for the power and wavelengths of the laser light.
