Method and apparatus for simultaneous block melting of material by laser |
摘要 |
A low cost method and apparatus for simultaneous block melting of a material by laser enabling completion of work in a short time. A laser beam from a YAG laser source etc. strikes a diffraction type optical element like a diffraction lens and is split into a large number of beams by diffraction and transmission. The beams are focused by a condensing lens etc. on a plastic surface as a large number of points or a line. The plastic is simultaneously heated to melt at these focused points for welding with another object or for removal. Therefore, no deformation occurs in the worked material like in the prior art where a surface was scanned by a focused point. The worked material may be a metal etc. in addition to a plastic. |
