| Abstract: | High power pulse-laser may be damaged by strong baleful overshoot in the pulse-laser dirver.To resolve the problem,we introduced a typical evaluation system with strong overshoot in this paper.After inspecting the source of the terrible overshoot particularly,a solution based on signal integrity(SI)with low cost was designed.Using SI knowledge to analyze this system carefully,to optimize all of the important transmission lines and reduce the EMI(Electro Magnetic Interference)of the laser driver,the performa... |
| Keywords: | pulse laser large current overshoot signal integrity(SI) |
