Embodiment Construction

[0029] The present invention will be further described below in conjunction with embodiment and accompanying drawing.

[0030] like figure 1 As shown, a multifunctional laser fusion diagnostic interferometer includes an illumination optical fiber 1, an illumination lens 2, a beam splitter 4, a beam splitter 2 7, an imaging lens 8, an imaging lens 10, an imaging lens 3 5, and stripes Camera one 9, streak camera two 11, streak camera three 6, optical circulator module A, probe optical imaging module B, interference module one C and interference module two D. The probe laser (illumination laser) is incident by the illumination fiber 1 and collected by the illumination lens 2. The probe laser is focused on the target surface 3 and reflected back to the Doppler signal light with the difference frequency signal. The Doppler signal light passes through the halo after splitting Shaper module A, probe optical image transmission module B, interference module 1 C, and interference modu...

Description

technical field [0001] The invention belongs to the technical field of laser measurement, and in particular relates to a multifunctional laser fusion diagnostic interferometer. Background technique [0002] The implosion of laser ablation target capsule is not only one of the effective ways to utilize fusion energy, but also an experimental method for high energy density physics research. During the compression process, the matter is often in an extreme state of high temperature and high pressure, and the interaction time between the laser and the matter is only on the order of nanoseconds. The acquisition of state information requires a special method. In the field of laser inertial-constrained diagnosis, the Velocity Interferometer System for Any Reflector (VISAR for short) uses the change in the movement of difference-frequency interference fringes generated by the optical Doppler effect to measure the shock wave velocity during the compression process. Conditions can be...
