Abstract: The device for protecting a low-voltage electrical power line against the overvoltages due to electromagnetic pulses which are nuclear in origin, consists of a limiting contact (12) inserted into the line, and a gas spark gap (14) connected between the line and earth. The gas spark gap fires after a few nanoseconds once the pulsed overvoltage appears, and causes a short-circuit which engenders the opening of the limiting contact (12). Once the current is interrupted, the limiting contact closes again thereby re-establishing the supply, the duration of opening of the limiting contact being sufficient for the extinction of the arc in the spark gap, avoiding any pre-priming during the establishment of the supply.   <IMAGE>

Abstract: A wavelength stabilized source of light has a laser diode (101) which emits a laser beam having a wavelength of 1.56 µm. Double harmonic generating means (105) generates double harmonic light of the laser beam. The double harmonic light enters to a resonator(102) having  87 Rb atoms. The resonator-(102) is irradiated with microwaves whose phase is modulated. The resonator (102) forms double resonance signals when the wavelength of the double harmonic light is equal to the resonance wavelength of  87 Rb and when the frequency of the microwaves is equal to the transition frequency of  87 Rb. A first control circuit (103) so controls the microwaves that the frequency of the microwaves will become equal to the transition frequency. A second control circuit (104) so controls the laser diode (101) that the wavelength of the double harmonic light will become equal to the resonance wavelength of  87 Rb. Therefore, the laser beam that is generated has a stable wavelength of 1.56 µm.
