摘要:
A method for measuring amplified spontaneous emission (ASE) content in a beam of laser radiation emitted by a laser master oscillator power-amplifier system comprises directing the beam of light into a two-beam interferometer having unequal beam path lengths. The two beams interfering in the interferometer have equal amplitude and form a pattern of interference fringes. The beam-path difference is arranged to be greater than the coherence length of the ASE so that the ASE content of the beam does not form interference fringes but provides a background level of light in the interference pattern. This enables the ASE content of the beam to be determined from measurements of the maximum intensity of a bright fringe and the minimum energy of a dark fringe in the interference pattern.

摘要:
The invention is an electronic writing device (50) and a method for creating an electronic signature, the device comprising a sensor (S1, S2, S2) for producing an output signal by detecting a dynamic parameter of a signature, and means for calculating a detected signature pattern on the basis of the output signal of the sensor (S1, S2, S2), comparing the detected signature pattern with a signature pattern stored in a memory and generating an enabling signal on the basis of the comparison, wherein the device also comprises a communication unit for implementing communication with a host system on the basis of the enabling signal. The device comprises a private key for the electronic signature and means for generating the electronic signature by means of the private key, wherein the communication unit is capable of receiving a data flow from the host system and supplying to the host system the electronic signature generated by means of the private key from the data flow.
