摘要: The millisecond Brillouin spectroscopy was developed and applied for the real-time observation of phonons in solid gas materials. spectra (polymethylmethacrylate) (air) at 300 K are observed over wave number range from k=8.1×104 m−1 to k=5.3×105 m−1. measurement time is only 100 ms, which by far shorter than that conventional method several minutes hours. technique would provide us with a useful tool dynamic thermal gas.
