<p>A laser oscillator comprises a control unit (1) and a laser unit (9), in which the control unit (1) generates control signals (I, T) for setting the power and the wavelength of the laser light generated by the laser unit (9) on the basis of wavelength values fed with the aid of a keyboard and the power of the laser light. In prior-art laser oscillators the relation between power and wavelength, on the one hand, and the two control quantities, on the other hand, is stored in a Table in the form of a ROM or RAM. For avoiding a very large Table required for a large number of possible values of the wavelength or the power, no Table is used in the laser oscillator according to the invention, but the control signals are calculated with the aid of an expression stored in the microprocessor 4. <IMAGE></p> |
