In this paper  photoresist melting method  which is low-cost  short-period and easy realization  is presented. In addition  the influence of photoresist melting on the groove profile of the photoresist grating is investigated. Experimental results show that the surface roughness reduces due to surface tension  when developed photoresist is heated to be melting state by this method. In experiment  when the melted photoresist grating is etched by ion beam  the surface relief grating possessing preferable groove profile is obtained on K9 glass substrate  then the surface is evaporated by aluminum using vacuum evaporation  holographic grating with preferable groove profile is successively fabricated.
