Embodiment 1

[0025] The present invention adopts "an independent adjustment system of chirp parameters for realizing two-color laser field" which has been applied for invention patent at the same time. The structure is as follows figure 1 shown. A beam splitter 10 is inserted at the entrance of the pulse compressor 5 of the femtosecond laser, and the light source is divided into two beams. One beam of light is connected with the optical path of a set of pulse compressor 5 and hollow fiber stretching and compression system 8, and the other beam The light is connected with the optical path of another set of pulse compressor 5 and hollow fiber stretching and compression system 8 after passing through the plane mirror B6, and then after passing through the mirror delay system 12 and the frequency doubling crystal 13, the two beams of light pass through a beam combiner 14 Combined into a beam of light, after passing through the reversible plane mirror 15, it is respectively connected with the h...

Abstract

The invention provides a method for regulating and controlling continuous generation of ultraviolet precise spectrums, having the characteristics that the chirp contents of single beam few-cycle pulses are regulated to generate ultraviolet precise spectrums in the forms of discrete spectrums, continuous spectrums, even-order spectrums and interference spectrums continuously during a higher harmonic method is used to generate ultraviolet precise spectrums; on the basis of stable generation of any form of ultraviolet precise spectrums, a second beam of few-cycle femtosecond light source are introduced to form a two-tone few-cycle femtosecond laser pulses; and the intensity, the chips, the polarization and the pulse width of the second beam of light source are changed and a beam combining piece is used to regulate the relative angles among lights in a two-tone field, thus realizing the real-time and multi-dimensional regulation and control on each form of selected ultraviolet precise spectrums. The method is simple and easy to operate and can be utilized to realize the multi-dimensional precise regulation and control.

Description

technical field [0001] The invention relates to a control method for the continuous generation of ultraviolet precision spectra, specifically adjusting the chirp content of period-level femtosecond pulses to continuously generate four types of ultraviolet precision spectra, and on this basis, using period-level The method of real-time and multi-dimensional regulation of various forms of spectrum by the dual-color field. Background technique [0002] The wavelength range of the ultraviolet spectrum is between visible light and X-rays, in the range of 10-400nm, and has special functions that other light sources do not have, such as: as a probe for biomedical research, military non-sensing radar, ultra-short atomic molecules Time probes and constructing superfield physics conditions and more. Therefore, ultraviolet spectroscopy has always been a hot spot of research scholars since the establishment of spectroscopy. At present, the method of obtaining ultra-fast ultra-intense ...
