Ultrafast Stretched-Pulse Fiber Laser Mode-Locked by Carbon Nanotubes
Ultrafast fiber sources having short pulses, broad bandwidth, high energy, and low amplitude fluctuations have widespread applications. Stretched-pulse fiber lasers, incorporating segments of normal and anomalous dispersion fibers, are a preferred means to generate such pulses. We realize a stretched-pulse fiber laser based on a nanotube saturable absorber, with 113 fs pulses, 33.5 nm spectral ...
متن کاملModeling Parabolic Pulse Formation in Mode-Locked Laser Cavities
Self-similarity is a ubiquitous concept in the physical sciences used to explain a wide range of spatialor temporal-structures observed in a broad range of applications and natural phenomena. Indeed, they have been predicted or observed in the context of Raman scattering, spatial soliton fractals, propagation in the normal dispersion regime with strong nonlinearity, optical amplifiers, and mode...
متن کاملPulse Dynamics in an Actively Mode-Locked Laser
We consider pulse formation dynamics in an actively mode-locked laser. We show that an amplitudemodulated laser is subject to large transient growth and we demonstrate that at threshold the transient growth is precisely the Petermann excess noise factor for a laser governed by a nonnormal operator. We also demonstrate an exact reduction from the governing PDEs to a low-dimensional system of ODE...
متن کاملStable Q-switched mode-locked Nd3+:LuVO4 laser by Cr4+:YAG crystal.
In use of saturable Cr(4+):YAG crystals, we have demonstrated the stable Q-switched and mode-locked (QML) operation of the Nd:LuVO(4) laser. The operation range of QML in use of the Cr(4+):YAG is larger than that use of SESAM and NLM. The obtained shape of Q-switched envelope, repetition rate and pulse energy are demonstrated to depend on the initial transmittance of the Cr(4+):YAG and reflecti...
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...
