In this episode: Laser spectroscopy searches for life on Mars, the latest quantum business news, and researchers demo diamond-based Raman vortex beams.

A system based on laser ablation ionization mass spectrometry could someday aid the search for signs of life on Mars. The setup—developed at the University of Bern in Switzerland—can detect microbe fossils in gypsum deposits found in Algeria, where the environmental conditions in which that gypsum was formed are similar to those on the Red Planet.

The quantum business sector is flourishing…Bosch is joining forces with Element Six to establish a spin-off venture specializing in quantum sensors. And Sparrow Quantum has secured funding to meet the growing demand for photonic quantum hardware and next-generation quantum chips.

An international team of researchers led by Hebei University of Technology in China is now harnessing the superior properties of diamond to overcome some conventional laser limitations.
