Summary: | The invention discloses an in-situ low-temperature high-pressure Brillouin spectral measurement system, and belongs to the technical field of optical equipment. The system structurally comprises a laser (1), a Brillouin light path system (2), a vacuum high-pressure sample accommodating system (3) and a signal acquiring and processing system (4) according to a light path sequence, and the vacuum high-pressure sample accommodating system (3) is connected with the cooling system (5). The invention provides a high-pressure Brillouin measurement system capable of reaching the lowest temperature of about 10K, and accurate low-temperature and high-pressure Brillouin spectral measurement can be carried out on a sample to be measured. According to the optical path, stray light can be simply suppressed by controlling the reflection angle to be the acute angle, and the signal-to-noise ratio is ensured. According to the low-temperature and high-pressure Brillouin spectrum system researched and developed by the invention, |
