摘要	There are many studies on phenomenon of periodic ripples induced by polarized lasers on the surface of metal, but studies on mechanism are few. Femtosecond laser is polarized through inserting a quarter waveplate into the beam path, and then vertically transmitted onto the surface of tungsten to produce ripples. And then the mechanism of the inducing ripples and influence of polarization of laser on the inducing ripples is studied. It is found that periodic ripples have a good correspondence with polarization of femtosecond laser. When the quarter waveplate rotates periodically of single direction, the polarization of femtosecond laser and the direction of periodic ripples change accordingly. The maximum inclining angle of ripples is about /4. An analysis of the mechanism of matter that direction of ripples changes along with rotating of quarter waveplate is given. Theoretical analyses indicate that the direction of periodic ripples induced by polarized laser is primary decided by electricity vector components grown at the moment of laser flies across birefringent crystals, for example a quarter waveplate. , 2015, Science Press.
