AB: Laser heating, interfaced with the diamond anvil cell (DAC) pressure generation technique, is a unique tool that allows experimental replication of the conditions of the deep Earth's interior. A unique on-line CO2 (10 micron wavelength) laser heating system has been designed and constructed at GSECARS, Sector 13 of Advanced Photon Source. The system is integrated into the existing fiber laser based setup (1 micron wavelength), and provides several advantages, including being able to directly heat materials that are transparent to near infrared laser light. The technical aspects of the heating system are presented, including the overall design, power control, switch between NIR and CO2 laser heating, sample alignment, temperature measurements, and monitoring of the heating process. X-ray diffraction measurements of silicates in DAC at high pressures and temperatures using the developed setup are presented.
