Diamond mirrors for high-powered lasers
May 2022, phys.org
High-powered lasers do high-powered damage, so the materials that interact with them (like a laser gun) need to be strong. Diamonds with nano-structures etched into them do the job.

'Life-like' lasers can self-organize, adapt their structure, and cooperate

I don't understand this at all. But I like the sound of it.
Next, the team will study how to improve the lasers' autonomous behavior to render them even more life-like.

Why lasers are being used to write inside diamonds
Oct 2022, BBC News
The laser can make atomic-scale changes to create circuitry inside the diamond. That could be useful for making instruments for radiation detection, where a diamond's durability is also an asset. Potentially such circuitry could also be used in quantum computers.
Researchers produce nanodiamonds capable of delivering medicinal and cosmetic remedies through the skin
Sep 2022, phys.org
Laser-based optical method quantifies nanodiamond penetration into layers of the skin and determines their location and concentration within body tissue in a non-invasive manner — eliminating the need for a biopsy. Much like trucks that make deliveries, artificial diamonds can deliver various medications to intended targets.
