| Abstract: | During the process of laser welding of an existent Nd:YAG laser manufacture system, some shortcomings might happen. The reason for such shortcomings was analyzed and the corresponding measures were pre-seuted to overcome them. Experimental results show that by modifying the incidence angle of the laser beam, adding two side nozzles and so on, the laser welding quality and the life of the optical apparatus could be improved dramatically. |
