In a recent study, the theory of pulse generation with fiber optical parametric amplification using sinusoidal (clock) intensity modulated pump was revisited [1]. This work showed that the pulses generated through such parametric interaction exhibit a shap ...
We propose a simple technique to realize Brillouin slow light in nearly transparent regime. A current-modulated semiconductor laser by a step function is used as Brillouin pump to generate a Brillouin loss doublet. ...
We here propose a novel technique for realizing the multiplication of the pulse repetition rate with a flexibly tunable multiplication factor, based on dynamic Brillouin grating (DBG) reflectors implemented in highly birefringent fibers. ...
We report 1.3-mu m mode-locked optically pumped semiconductor disk laser (SDL) made by wafer fusion. The gain medium and the saturable absorber, both based on an InP material system, were integrated with AlGaAs-GaAs distributed Bragg reflectors by localize ...

With the arrival of mode locking for Q-switched lasers to generate ultra short light pulses, a method to measure their expected time duration in the psec range was needed. A novel method, based on an intensity correlation measurement using optical second h ...
Femtosecond pulses focused in glass substrate induces various modifications in the material depending on the fluence level and laser exposure conditions. Upon increasing pulse energies above the energy threshold for non-linear absorption, femtosecond laser ...
The impact of Raman scattering and modulation instability is studied in Brillouin time-domain analysis systems. It turns out to be very detrimental for long-range sensing as a result of the extended interaction length combined to the high pump peak pulse p ...
The wavelength tuning properties of a tunable external cavity laser based on multiplexed volume holographic gratings and a commercial micromirror device are reported. The 3x3x3 cm(3) laser exhibits single mode operation in single or multi colors between 77 ...
We present a novel and highly efficient temporal pulse shaping technique for the generation of flattop-like picosecond pulses in the deep UV. Using standard sum frequency generation (SFG) of a Ti:sapphire laser but with a pair of properly chirped beams pri ...
We report on dynamical observations of femtosecond-laser-generated bubbles in water using a single-laser-source pump/probe setup combined with stroboscopic imaging. With this simple setup, we accurately measure the transmission of a probe beam and simultan ...
