摘要：

Sub-wavelength　periodical　grating　structures　on　tungsten　surface　was　fabricated　by　femtosecond　laser　whose　central　wavelength　is　800　nm　and　the　repetition　rate　is　1　kHz.　The　period　of　the　structures　was　349-620　nm　when　the　laser　incidence　angle　was　0°-80°.　The　formation　of　grating　structures　on　tungsten　was　discussed　by　surface　plasmon　polaritons　theory　and　the　result　of　experiment　showed　a　good　agreement.　The　reflectance　spectra　of　these　grating　structure　was　simulated　by　rigorous　coupled　wave　analysis　method.　The　enhanced　absorbtion　peak　was　closed　to　the　grating　period.　This　study　gives　a　prospect　of　applications　by　femtosecond　laser　fabricating　grating　structures.　©　2016,　Beijing　University　of　Technology.　All　right　reserved.
