We demonstrate free-beam spectral self-compression of ~100-GW femtosecond laser pulses due to self-phase modulation (SPM) in a transparent dielectric. While all the earlier studies of SPM-induced spectral narrowing have been performed using optical fibers, experiments and simulations presented in this Letter show that this type of spectral transformation can be implemented as a part of a full three-dimensional field-waveform dynamics and can be extended to peak powers ∼10 times higher than the critical power of self-focusing. With a properly chosen initial chirp, spectral self-compression is accompanied by pulse compression, providing spectral-temporal mode self-compression as a whole.

- Thermogenetics is an innovative neurostimulation technique that uses thermosensitive TRP cation channels to activate neurons.
- This study demonstrates rapid and reproducible activation of snake TRPA1 channels in various cell types and live organisms using infrared (IR) laser radiation.
- The research introduces a fibre-optic probe that enables precise temperature measurements at a single-cell level, allowing for mild heating and safe neuronal activation without damaging the cells.
