All-fiber-integrated supercontinuum generation is demonstrated from ~0.9-3.6 mum with ~0.7 W time-averaged power by using a telecommunication laser diode, amplified by an erbium/ytterbium co-doped cladding-pumped fiber amplifier, and coupled into 35 m ZBLAN fluoride fiber.
Third order cascaded Raman shifting is used to generate light to 1867 nm in sulfide fibers, and the nonlinearity is measured to be ~5.7 times 10-12 (m/W). Damage at ~1 GW/cm2 limits the wavelength shift range.
Summary form only given. We synchronize two passively modelocked Er:doped fiber lasers of pulse width 4.5 ps by using a novel acousto-optic modulator and grating scheme. By measuring the cross-correlation of the two lasers, the interlaser jitter is extracted to be 1.3 times the pulse width. The temporal locking of lasers is important for telecommunication networks, measurement systems, and spectroscopy.
Summary form only given. By taking advantage of the well-developed models for nonlinear pulse propagation in optical fibers, we indirectly measure picosecond laser pulse characteristics such as chirp and pedestal energy. Measurements of output pulse-width versus launched power through a short test fiber, along with the time band-width product of the launched pulse, are fed into a routine to find the...
