Method and device for determining the time of actuation of the system of thermostabilization of the active length of the resonator of lasers a frequency stabilized

摘要

According to the process, in order to determine the time of actuation of the system of thermostabilization of the active length of the resonator of lasers with stabilized frequency, after the connection of the supply of the laser tube, is continuously the electrical signal is dependent on the temperature of the laser resonator, which is compared to a reference electrical signal and in the equalization of the two signals, the system of thermostabilization of the active length of the resonator of the laser to be stabilized frequency is actuated. / p & & p & the device in order to carry out this determination of the time of actuation of the system of the active thermostabilization comprises a comparator 1 whose output is connected to the control input of the system of the active thermostabilization 12. Its first input is connected to the block for generating the electrical signal, which is constituted by two receivers photo - 5 and 6 of the system of thermostabilization 12. Its second input is connected to the source of a reference signal g. the connection with the first input of comparator 1 is carried out by a differential amplifier 9, a shaping 10 and an integrator 11 which are connected in series. / p & & p & the process and device described above - above are used in the production of devices for measuring the laser.
