Embodiment
[0034] Such as Figure 5 As shown, a functional module for suppressing waveform distortion includes a pulse input module 1 for emitting seed light; in this embodiment, the pulse input module 1 includes a semiconductor laser and its driving board;
[0035] The waveform distortion suppression module 2: used to adjust the rising edge of the input pulse, and then suppress the waveform distortion; in this embodiment, it includes a function generator 2-1 (the function is an exponential function) and a pulse rising edge editor 2-2 ;
[0036] The function generator 2-1 is as Image 6 As shown, it includes the "switch group" 2-1-1 for generating time delay (the number of switch groups is N=7, the more the number of switches, the higher the function accuracy), and the "switch group" for superimposing signals with different time delays Signal Adder" 2-1-2, and "Low Pass Filter" 2-1-3 for filtering out noise. Set the closing time and current of each switch through the "Switch Group", a...
