Embodiment Construction
[0019] The present invention will be further described below in conjunction with the embodiments and accompanying drawings, but the protection scope of the present invention should not be limited thereby.
[0020] When the high-energy ultra-short pulse works according to the design value, the output state is: energy 1000J, pulse width 1-10ps adjustable, and the corresponding power is 10 +15 W. In the technical solution proposed by the present invention, in order to realize the parameter diagnosis of the laser pulse under this condition, the high-energy ultrashort pulse becomes the measured pulse 1 after passing through a sampling mirror. The transmittance of the sampling mirror is T=1.5%. The measured pulse 1 first enters the first beam splitter 2 , and then enters the dual-channel second beam splitter 6 through the first lens 3 , the gate aperture plate 4 , and the second lens 5 . After the measured pulse 1 leaves the second spectroscope 6, two diagnostic pulses are output ...
