Rare-earth doped chalcogenide fiber extends photon storage lifetime while maintaining high absorption efficiency through Zeeman splitting.
An all-fiber system generates temporally coherent supercontinuum pulses using self-phase modulation in a microstructured fiber.
Segmented multilayer claddings enable low refractive index cores by providing effective reflection without requiring lower index materials.
Sharp electrode pins ionize air near a Q-switch crystal to neutralize surface charges without external power.
Dual-core fiber amplifier mitigates modal instability to scale output power beyond 10kW while reducing quantum defect heating.
