Laser-as-a-Sensor approach shrinks oxygen sensing volume to sub-nanoliter

A paper (Wang 2026) on monolithically integrated active-cavity "laser-as-a-sensor" embeds the sensing element inside the laser cavity for oxygen detection, cutting the sampling volume to sub-nanoliter levels, though sensitivity shows no clear improvement.
