Abstract： |
A HeNe laser capable of emitting two vertical polarizations with stable light intensity, which contains laser gain pipe with high reflectance tail light output mirror and anti-reflection window piece in tow sides, a main light beam output mirror in one side of anti-reflection window piece, transverse magnetic field generator and small frequency difference generator which is a double fraction crystal located between anti-reflection window piece and main light beam output mirror, the laser fixed on support frame and has advantages of small light intense fluctuation, fine stability and strong interference resisting. |
