摘要： The present invention relates to Wavelength Division Multiplexing (WDM) based optical communications, and more particularly to an Fabry-Perot (FP) laser apparatus mode-locked to a multi-frequency lasing light source and an optical transmission apparatus using the same. An FP laser apparatus mode-locked to a multi-frequency lasing light source, comprises an optical amplifier that amplifies inputted optical signals, a laser light source that wavelength division demultiplexes part of the inputted optical signals, multiplexes the demultiplexed optical signals, re-transmits the multiplexed optical signals, wavelength division demultiplexes the remaining part of the amplified optical signals, and outputs signals mode-locked to the demultiplexed signals, and a first circulator that inputs the remaining part of the amplified optical signals into the laser light source, and outputs, to an optical transmission link, optical signals mode-locked to the multi-frequency lasing light source outputted from the laser light source.

摘要： The invention relates to a passively mode-coupled femtosecond laser whose ring resonator comprises the following elements: a) a laser-active element (1); b) at least one dielectric mirror (2), which has a negative group velocity dispersion (GGD) such that, for a coherent portion of the optical spectral region that is capable of being amplified by the laser-active element (1), the sum of the group velocity dispersions of the mirror (2) and of the positive group velocity dispersion of the laser-active element (1) is negative (see formula (a)); c) two concave mirrors (21) and (22) which are adjacently arranged next to the laser-active element (1) in a spatial manner and which are oriented with the concave surfaces thereof toward the same, and; d) an optical decoupler (3). The optical path length in the resonator is less than 60 cm, preferably less than 30 cm, especially less than 15 cm. The focal distances f21 and f22 of the concave mirrors (21) and (22) are less than 3 cm, preferably less than 2 cm, especially less than or equal to 1.5 cm such that it is possible to attain a highly repetitive generation of femtosecond pulses. The invention additionally relates to a continuously variable highly-repetitive femtosecond laser, to the use of the same for carrying out the highly-repetitive generation of femtosecond pulses and to a method for tuning the same.

摘要： L'invention concerne les cavités optiques dites instables dans lesquelles est créé un faisceau laser dont une partie est volontairement perdue pour servir hors de la cavité.
Des changements de direction (A, B, C, D) sont imposés, dans la cavité, au faisceau laser pour lui faire parcourir un trajet optique dit en anneau.
Pour s'affranchir des problèmes de tenue au flux des miroirs habituellement utilisés, il est proposé d'utiliser des prismes (Ps, P1, P2, P3) dont une face, utilisée en réflexion totale, assure les changements de direction (A, B, C, D).
Application en particulier dans le domaine des cavités laser et des oscillateurs paramétriques optiques.

摘要： A loop four-wave mixing phase conjugator that can be used with depolarized signal beams comprises a polarization separator (10), a polarization mixer (19), an optical diode (20), a gain medium (22) and relay optics (14, 16) that together form a unidirectional laser resonator. In operation, the polarization separator separates a signal beam (ε 1 ) into orthogonally polarized signal beam components (ε 11 ) and (ε 12 ) and directs them to a nonlinear medium (12). The components propagate through the nonlinear medium and emerge as loop beam (ε 2 ), with orthogonally polarized components (ε 21 ) and (ε 22 ). The polarization mixer mixes the energy from the two orthogonally polarized loop beam components, and relay optics direct the loop beam components back to the nonlinear medium at an angle with respect to the input beam. The loop beam components intersect and optically interfere with signal beam components (ε 11 ) and (ε 12 ) in the nonlinear medium to form gratings (18). The optical diode and gain medium are positioned in the optical loop so that an oscillation beam (ε 3 ) builds up from optical noise in the resonator and oscillates in a direction counter to the propagation direction of loop beam components (ε 21 ) and (ε 22 ). A portion of oscillation beam (ε 3 ) is transmitted by the gratings, and exits the optical loop as an output beam (ε 4 ). (ε 3 ) is phase conjugate to the input beam (ε 1 ) in both the spatial and polarization senses.

摘要： A solid state laser comprises a cavity resonator in the form of a generally cylindrical body and, located within the resonator, an active region which generates lasing light when suitably pumped. The resonator has a relatively high effective refractive index (n > 2 and typically n > 3) is sufficiently deformed from circularity so as to support at least one librational mode (e.g., a V-shaped or a bow-tie mode, the latter being presently preferred for generating relatively high power, directional outputs). Specifically described is a Group III-V compound semiconductor, quantum cascade (QC), micro-cylinder laser in which the resonator has a flattened quadrupolar deformation from circularity. This laser exhibits both a highly directional output emission and a three-order of magnitude increase in optical output power compared to conventional semiconductor micro-cylinder QC lasers having circularly symmetric resonators.

摘要： A wavelength converter comprises a loop of optical fibre having an entry end (14) and an exit end (16). The entry end of the loop forms an input for a pump wavelength and the exit end forms an outlet for a converted signal. The loop is arranged to produce Stokes shifted wavelength components from a pump wavelength by Raman effect. A wavelength selective coupler (18) is provided between the entry and exit end (14, 16) of the loop. The coupler permits exit of a predetermined wanted Stokes shifted wavelength component but causes coupling of lower order Stokes wavelengths to the entry for recirculating in the loop to enhance generation of the predetermined wavelength component.
