Dispersive-wave mechanism of interaction between ultrashort pulses in passive mode-locked fiber lasers

Mode Locked Fiber Lasers

Single Crystal Fiber for Ultrashort Pulses Lasers

Driven by the micromachining industry, where short pulses mean precision and power equals process speed, short pulse width high power lasers are in high demand. Whereas the MOPA (Master Oscillator Power Amplifier) is the current preferred architecture, it still suffers from performance limitations and high costs associated with system complexity and power amplifier limitations. A new amplifier ...

Mode-locked ytterbium fiber lasers.

A compact fiber laser is demonstrated with use of a Gires-Tournois compensator and a short length (2-4 cm-long) of highly doped ytterbium (Yb) fiber providing net anomalous group-velocity dispersion. With use of a novel semiconductor saturable absorber mirror based on GaInNAs structure, self-started 1.5-ps-pulse mode-locked operation was obtained at 1023 nm with a repetition rate of 95 MHz. A m...

J ul 2 00 1 Spectral characteristics of ultrashort pulses in Kerr - lens mode - locked lasers

A number of factors that influence spectral position of the femtosecond pulse in a Kerr-lens modelocked Cr:LiSGaF laser have been identified: high-order dispersion, gain saturation, reabsorption from the ground state, and stimulated Raman scattering. Using the one-dimensional numerical model for the simulation of the laser cavity, the relative contributions of different factors have been compar...

Intensity noise of mode-locked fiber lasers.

Intensity noise of mode-locked fiber lasers is characterized systematically for all major mode-locking regimes over a wide range of parameters. We find that equally low-noise performance can be obtained in all regimes. Losses in the cavity influence noise strongly without a clear trace in the pulse characteristics. Given that high-energy fiber laser oscillators reported to date have utilized la...
