Pulses from an ultrafast oscillator are conditioned, amplified, and delivered in an all-optical-fiber architecture. Combined with an electro-optic receiver, the complete system delivers a 4-V electrical trigger with less than 400 fs additive jitter.
Heating a photo-darkened ytterbium fiber causes a recovery in spectral transmission to the pre-darkened state. Exposure to H2 at high temperatures causes a permanent change in the visible transmission identical to that caused by photo-darkening.
We report optical amplification in a bismuth-doped silica fiber at 1308 nm with 810 nm excitation and demonstrated simultaneous optical amplification at two wavelengths near 1300 nm region. This wavelength is the closest to the important telecommunications window.
We demonstrate a simple, all-fiber technique for removing nonlinear phase on a pulse-to-pulse basis in a fiber-based CPA system. Removal of 1.0 pi of nonlinear phase is achieved.
