Laser beam drilling (LBD) is one of the advanced machining processes that are used for the machining of such materials like metals and its alloys, non-metals, composites, ceramics because of its precision, low cost and high speed of operation which cannot be machined with the conventional machining processes. This paper is focused the effect of Nd:YAG laser on the hole quality of composites materials. Moreover, the review paper has been more emphasized on increasing the productivity of the drilled hole by using the solid-state laser without changing the drilled hole. This paper is shown the future scope in the area of solid-state drilling through laser of composites. This review paper may be beneficial for the researchers who are working on the laser drilling of composites.
