Wideband-tuneable, nanotube mode-locked, fibre laser.
Ultrashort-pulse lasers with spectral tuning capability have widespread applications in fields such as spectroscopy, biomedical research and telecommunications. Mode-locked fibre lasers are convenient and powerful sources of ultrashort pulses, and the inclusion of a broadband saturable absorber as a passive optical switch inside the laser cavity may offer tuneability over a range of wavelengths...
متن کاملUltrafast all-fibre laser mode-locked by polymer-free carbon nanotube film.
This work for the first time reports the results on study of a polymer-free carbon nanotube (CNT) films used as a saturable absorber in an all-fibre laser. It is demonstrated that free-standing single-walled CNT films fabricated by an aerosol method are able to ensure generation of transform-limited pulses in an Er all-fibre ring laser with duration of several picoseconds and high quality of mo...
متن کامل152 fs nanotube-mode-locked thulium-doped all-fiber laser
Ultrafast fiber lasers with broad bandwidth and short pulse duration have a variety of applications, such as ultrafast time-resolved spectroscopy and supercontinuum generation. We report a simple and compact all-fiber thulium-doped femtosecond laser mode-locked by carbon nanotubes. The oscillator operates in slightly normal cavity dispersion at 0.055 ps(2), and delivers 152 fs pulses with 52.8 ...
متن کاملMode-locked fiber laser gyroscope.
We propose and demonstrate a novel fiber-optic gyroscope in the form of a mode-locked laser consisting of a laser cavity formed by a planar mirror at one end, a gain medium, and a Sagnac interferometer at the other end. The Sagnac interferometer serves as a reflector as well as a rotation-sensing element. The output of the gyroscope is a series of short optical pulses. The separation of two set...
متن کاملGraphene mode-locked ultrafast laser.
Graphene is at the center of a significant research effort. Near-ballistic transport at room temperature and high mobility make it a potential material for nanoelectronics. Its electronic and mechanical properties are also ideal for micro- and nanomechanical systems, thin-film transistors, and transparent and conductive composites and electrodes. Here we exploit the optoelectronic properties of...
