Application of Laser Technology for Static and Dynamic Compression Experiments

Laser, different from other light sources in that it emits light with a single wavelength coherently, spatially and temporally, is one of the most applicable tools for high-pressure experiments. Here I introduce three experimental techniques using the laser; (1) both-sided CO2-laser heated DAC system, (2) laser-shock compression technique coupling with DAC, and (3) Brillouin and Raman spectroscopies combined with CO2-laser heated DAC system. The newly-developed techniques were proposed as promising ways to access new material conditions, to determine temperature accurately, or to identify phase transitions including melting, toward explorations of new material phase regimes.
