Temperature gradients in the laser-heated diamond anvil cell

The influence of wavelength-dependent absorption and temperature gradients on temperature determination in laser-heated diamond-anvil cells

New Developments On Laser Heated Diamond Anvil Cell

New developments on laser heated diamond anvil cell are reported by introducing a system installed at the Advanced Photon Source (APS). With the system, a laser heating spot of 20 40 μm in diameter can be generated to temperatures over 3000 K for samples in diamond anvil cell; and the temperature gradients in the laser heated volume are less than 100 K. The system is based on the double sided l...

In situ Raman spectroscopy with laser - heated diamond anvil cells

We have built a micro-optical spectroscopy system coupled with a Nd:YLF laser heating system for performing high pressure–temperature in situ Raman measurements in diamond anvil cells (DAC). A variety of materials can be investigated, providing information about structural and dynamical properties of condensed matter under extreme conditions. We report on a method for laser heating transparent ...

In situ high pressure-temperature Raman spectroscopy technique with laser-heated diamond anvil cells

We describe an in situ high pressure-temperature Raman technique for studying materials in laser-heated diamond anvil cells using a Nd:YLF laser s1053 nmd as the heating source and an ion laser as the Raman exciting source. Here we introduce the method of laser heating transparent samples using a metallic foil (Pt,Re, or W) as the laser absorber (internal heating furnace) in a diamond cell. The...
