Degenerate four-wave mixing spectroscopic technology-based method for determining historical relic producing area
A technology of four-wave mixing and spectral technology, which is applied in the field of cultural relic origin measurement based on degenerate four-wave mixing (DFWM) spectral technology, can solve the problem of non-destructive and near-non-destructive testing, which cannot be widely used, and the consumption of mass spectrometry technology. Large sample volume and other problems, to avoid background interference, avoid the same weight interference, reduce the effect of sampling

Embodiment 1
[0027] Prepare the test device as follows:
[0028] The laser is selected to emit a laser whose central frequency is the same as the resonance frequency of the energy level of the lead atom. The laser line width is smaller than the spectral interval of the lead atom isotope, and the laser can be continuously tuned near the energy level resonance frequency of the lead atom isotope. Specifically, a continuously tunable narrow-bandwidth ring dye laser or a semiconductor laser is selected.
[0029] There are 6 identical all-reflective mirrors. According to the frequency of the laser emitted by the laser, the all-reflective mirrors are coated with a 45° high-reflection film (>99%) in the laser frequency range.
[0030] 3 identical half-wave plates, choose the half-wave plate applicable to the laser frequency range.
[0031] There are 4 identical polarization beam-splitting cubes, and the polarization beam-splitting cube applicable to the laser frequency range is selected.
