Embodiment 1
[0016] figure 1 It is a schematic diagram of an ultrashort laser pulse waveform measuring device of the present invention, figure 2 It is a side view of the double frequency optical path in the present invention, figure 2 Yes figure 1 A side view of the figure 1 , figure 2 Among them, in an ultrashort laser pulse waveform measuring device of the present invention, a beam splitter 1 is arranged in the incident direction of the high-power laser pulse; the laser pulse is divided into transmitted light and reflected light by the beam splitter 1.
[0017] On the reflected light path of beam splitter 1, there are mirror 2, beam expander collimator mirror 3, double prism 4, frequency doubling crystal 5, and light blocking sheet I6; the reflected light of beam splitter 1 is reflected by mirror 2 to the beam expander The collimator 3 performs beam expansion, and the obtained expanded beam is divided into upper and lower parallel lights by the double prism 4, and is incident on t...
