Abstract: An ESD clip for protecting an integrated circuit against electrostatic discharge comprises two mutually opposed pressure bodies interconnected by a spring for short-circuiting connection pins of the integrated circuit. The pressure bodies of the ESD clip are pressed against one another by the spring and in that the pressure bodies are coated with an electrically conducting supporting material. Only minimal mechanical moments are thus exerted on the connection wires of an integrated circuit, so that they are not or hardly deformed.

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.

Abstract: In an optical transmission device comprising a plurality of semiconductor lasers (.lambda..sub.1, . . . , .lambda..sub.N) for transmitting an equal plurality of information streams, the wavelengths of the radiation beams from the lasers are stabilised by successively selecting them and then measuring them by means of a wavelength meter (20) and subsequently by correcting them. Since the wavelength of the radiation emitted by each laser may vary within limits imposed by neighbouring wavelengths, a high measuring rate of the wavelength meter is not required.
