Self-organized optofluidic locking enables stable single-frequency lasing in dynamic liquid media

Liquid-state lasers are promising wavelength-agile, reconfigurable coherent light sources, but fluid gain media introduce Brownian motion, thermal transport, and refractive-index fluctuations that destabilize single-frequency emission. Here, we demonstrate that nonequilibrium flu...

Curving transparent ceramics via force-driven sintering

Transparent ceramics are critical for advanced optics and armor, but shaping them into highly curved geometries without degrading their optical and mechanical properties remains a formidable challenge. Here, we introduce a force-driven sintering strategy that harnesses force-indu...
