Bioinspired high-power-density strong contractile hydrogel by programmable elastic recoil

Science Advances, 2020
Catapult-like hydrogel actuator delivers high contraction power. Stimuli-responsive hydrogels have large deformability but—when applied as actuators, smart switch, and artificial muscles—suffer from low work density due to low deliverable forces (~2 kPa)

High power coupled CO2 waveguide laser array [PDF]

, 1986
A hollow-bore ridge waveguide technique for phase locking arrays of coupled CO2 rf excited waveguide lasers was demonstrated. Stable phase-locked operation of two- and three-channel arrays has been demonstrated at the 50 W output level.

Optical Fiber for High-Power Optical Communication

Crystals, 2012
We examined optical fibers suitable for avoiding such problems as the fiber fuse phenomenon and failures at bends with a high power input. We found that the threshold power for fiber fuse propagation in photonic crystal fiber (PCF) and hole-assisted ...
