专利汇可以提供Method for the frequency stabilization of a laser专利检索,专利查询,专利分析的服务。并且A method for the frequency stabilization of a laser, in particular for a He-Ne laser is described whereby the active medium is situated between a fixed mirror and a movable mirror which can be translated along the axis of the laser by a piezo ceramic, and the laser radiation is circularly polarized by means of a small lambda /4 polarizing plate and passes through an absorption tube located within a magnetic coil which is part of a resonator loop and filled with the laser-active gas, and a photosensitive element behind the absorption tube and outside the resonator produces a signal, via amplifiers and demodulating devices for controlling the piezo ceramic. The control signal is proportional to the frequency deviation of the laser radiation from the center frequency gamma 0. The method is particularly characterized by the intensity modulation of the laser radiation which is produced due to the alternating effect of the alternating magnetic field in the absorption tube and which depends on the center frequency gamma 0 at the inverse Lamb-dip being utilized for the production of the control signal.,下面是Method for the frequency stabilization of a laser专利的具体信息内容。
