Abstract
Demonstrations of acousto-optic effects in fluorescent samples are widespread but their utility is generally limited due to the small amplitude modulations achievable and concurrently, long acquisition times. Here, we report the observation of a novel, gigantic acousto-optic modulation of two-photon excited fluorescence. The effect’s magnitude when applying low intensity ultrasound allows high SNR modulation of fluorescence in standard multiphoton systems without sophisticated detection schemes and without the need for extensive temporal averaging or signal processing. We observe this effect in the brain of awake behaving mice, demonstrating its utility for future advanced AO applications in vivo.
