For more than 30 years, scientists have known that oxygen can become metallic when subjected to extreme pressures. Yet despite this remarkable discovery, the vibrational properties of metallic oxygen have remained largely unexplored. Recent research has now changed that.
The August cover story of Photonics Views highlights how researchers successfully identified the long-sought Raman signature of metallic oxygen using 3 highly stable single-frequency lasers in the Cobolt 04-01 Series: Cobolt Samba at 532 nm, Cobolt Flamenco at 660 nm, and Cobolt Disco at 785 nm.
The editorial explores the significance of this breakthrough, the role of Raman spectroscopy in uncovering the properties of extreme materials, and what these results could mean for future high-pressure physics research.
