Fiber amplifiers for coherent space communication

René Dändliker

We report on the application of double-clad doped fiber amplifiers for coherent space communication systems using a master oscillator power amplifier (MOPA) design at 1.06 μm. The master oscillator is either a single-frequency Nd:YAG solid-state laser or a ...

Spectral hole burning in naphthalocyanines derivatives in the region 800 nm for holographic storage applications

Demetri Psaltis

Persistent spectral hole burning is studied for several free-based and metallo-naphthalocyanine derivatives in polymer hosts. These materials exhibit a strong 0-0 absorption band in the region 800 nm matching the wavelength range of most semiconductor diod ...

Laser linewidth determination in the sub-Megahertz range using a Brillouin fibre laser

Luc Thévenaz, Philippe Robert

The Brillouin fibre laser has experimentally demonstrated its suitability for the measurement of laser linewidth in the 1 kHz to 500 kHz frequency range. A major advantage of this system is to be widely independent of the source wavelength by generating th ...

Etude de l'amplification optique et de sa saturation dans les puits quantiques

We study the optical properties of strongly photo-excited GaAs/AlxGa1-xAs Quantum Wells in the one-dimensional optical amplifier geometry. One part of our work deals with gain measurements using the "variable stripe length method". We are proposing two new ...

Extension of the Free-Electron Laser-Amplifier Code Tda to Resonator Configurations

Trach-Minh Tran

The investigation of many interesting, complex phenomena in a free-electron laser (FEL) requires the use of numerical computer codes. In this paper we describe the extension of one such code (TDA), which in its original form could only be used to study fre ...

Gain Measurements in Ingaas/Ingaasp Multiquantum-Well Broad-Area Lasers

Franz-Karl Reinhart, Marc-André Dupertuis

The paper describes gain measurements in InGaAs/InGaAsP multiquantum-well lasers at 1.55-mu-m derived from the spontaneous emission under current injection. The gain spectrum in a broad-area laser device is determined from the spontaneous emission spectrum ...

Time domain reflectometry in the micrometer range

René Salathé, Paul Beaud

The subpicosecond OTDR has been investigated as a diagnostic tool for the fiber optics components and integrated waveguide devices. The mode-locked dye laser at 1.3 μm was excited by Nd-YAG compressed pulses. 300 fsec pulses have been generated at the r ...

Interferometric measurement of the elongation of a pulsed diode laser

René Salathé

An interferometric technique was developed for detecting fast displacements of small areas in beam direction by less than λ/8. It utilizes a modified Michelson interferometer and a He-Ne laser light source. The technique was applied to measure the t ...
