Despite decades of rapid development, the response times of electronic detectors are still orders of magnitude behind the time scales achieved and dealt with in Ultrafast Optics and Photonics. In these fields, researchers routinely experiment on phys
We report the generation of high-peak-power picosecond optical pulses in the 1.55 μm spectral band from a monolithically mode-locked laser integrated with a pulse selector and power booster. High-peak-power (>1 W) pulses with durations of 15.4 ps at

We report a 166 W burst mode pulse fiber amplifier seeded by a Q-switched mode-locked all-fiber laser at 1064 nm based on a fiber-coupled semiconductor saturable absorber mirror. With a pump power of 230 W at 976 nm, the output corresponds to a power

Principles of pulse shaping aiming larger pulse energy in fiber lasers are reviewed. From conventional solitons generated in the anomalous dispersion regime, stretched pulses in dispersion-managed fiber lasers, similaritons in normal dispersion regim

A hybrid grating–prism dispersion eraser is proposed to achieve broadband dispersion compensation. A ray-tracing model is built up for its phase spectrum and derivatives. The numerical calculation shows that the eraser can compensate dispersion up

Because of the special needs for nanosecond double pulse applications in micromachining and material processing, we demonstrated a stable nanosecond dual-pulse erbium-doped fiber laser based on nonlinear polarization rotation technology. The fiber la

We propose a processor based on the concatenation of two fractional temporal Talbot dispersive lines with balanced dispersion to perform the DFT of a repetitive electrical sequence, for its use as a controlled source of optical pulse sequences. The e

Numerical simulation of Gain Switching in Quantum Cascade Lasers (QCLs) for short pulse generation in the mid-Infrared region is reported. Standard two-level rate equation model is used to analyse the QCL which consists of 48 periods of injector and

A three-dimensional non-adiabatic model in combination with a rate equation model is used to characterize high-intensity (>10 16 W/cm 2 ) femtosecond laser pulse propagation in atomic gas medium. In these conditions the atoms in the target gas will b

We have demonstrated experimentally that few-cycle pulses can be achieved from an Er-doped fiber laser via single-stage soliton compression. Adopting negative prechirp amplification is to avoid the high-energy pulse break-up and increase the spectral
