In recent years,the rapid development of 3 D printing technology has been hailed as the "third industrial revolution". In order to improve the printing speed double 3 D printer,3 D printing equipment reduce volume weight,improve portability,this paper design and manufacture for a high repetition rate,high power 3 D printing UV laser modulation source. The purpose of this paper is to design a switching modulation circuit for driving high-speed UV laser diodes( LDs). Firstly,the laser high speed modulation constraint technology and the threshold characteristics of semiconductor lasers are introduced. Then,the switching system of the high-speed ultraviolet LD is designed,and the matching optical design system and the mechanical design system are designed to realize the concrete high speed,high power ultraviolet Modulation source; finally,the high frequency,high power UV LD performance test,to meet the requirements of indicators.
