An all-fiber phase-modulated master oscillator power amplifier for free-space coherent communication is presented. A distributed-feedback fiber laser at 1.06 μm is used as master oscillator. A novel phase modulator based on a ZnO-coated single-mode fiber m ...
PURPOSE: Examination of morphology in corneal ablation induced by a q-switched Er:YSGG (2.79 mu m) laser and a free-running Er:YAG laser (2.94 mu m). ...
Among all non-linear optical effects observed in single-mode optical fibres, stimulated Brillouin scattering (SBS) is of particular importance since it has numerous practical implications. SBS occurs when laser waves are scattered through the interaction o ...
We present the design of a highly efficient, pulsed ammonia laser which is optically pumped by a commercial TEA CO2 laser and is line tunable in the spectral range of 780-930 cm(-1). The power, spectral, and temporal characteristics of the laser have been ...
Hill et al. reported for the first time in 1978 the formation of refractive-index gratings in germanium doped silica fibers exposed to UV laser radiation. Since then many studies have been performed on fiber gratings and a widespread range of applications ...
We report the first demonstration of an extremely simple and efficient 1.24 μm phosphosilicate fiber-based Raman laser with Bragg gratings written directly in the fiber used. The laser pumped by Nd fiber laser exhibits a slope efficiency of 80% ...
Rare-earth doped fibers can be used to realize simple, compact sources of ultrashort pulses. To date, considerable effort has been developed to obtain short pulse generation in Er3+-doped fiber lasers at 1.55 µm. Contrary to this, little work has bee ...
We present a monolithically integrated coupled cavity vertical cavity surface emitting laser or BiVCSEL: this two-terminal electrically injected device exhibits stable laser emission at two design wavelengths simultaneously. The coupling between the two mo ...
We report on the experimental results of a dual-stage amplifier combining a Nd-doped double-clad fiber and a Nd-doped YAG crystal. We obtained up to 3.5-W single-mode single-frequency output power with 28-dB gain. This is, to the best of our knowledge, the ...
A complete set-up for local annealing of Shape Memory Alloys (SMA) is proposed. Such alloys, when plastically deformed at a given low temperature, have the ability to recover a previously memorised shape simply by heating up to a higher temperature. They f ...
