Multi-pulse accumulation of gas molecular coherence enables gigahertz ultrafast frequency conversion
Yazhou Wang, Marcello Meneghetti, Ian Davidson +8
Frequency conversion of ultrafast lasers is fundamentally constrained by the trade-off between pulse energy and repetition rate, limiting access to regimes critical for fundamental…

Photoacoustic methane detection assisted by a gas-filled anti-resonant hollow-core fiber laser
Cuiling Zhang, Jose Enrique Antonio-Lopez, Rodrigo Amezcua-Correa +2
Photoacoustic spectroscopys (PAS)-based methane (CH4) detectors have garnered significant attention with various developed systems using near-infrared (NIR) laser sources, which re…
