【Abstract】 In this paper,the polarization properties of output beams of internal mirror He-Ne laser is simply described. The main causes which effects the polarization properties and the influencs o?polarization flip on the use of instrument are analysed. The construction of several types of He-Ne lasers obtained linear polarization of laser beams is introduced. The advantages pf realizing the linear porization of internal mirror He-Ne lasers by a strong transverse magnetic field are also pointed out.更多还原
