摘要： The invention concerns a wideband optical gate in the domain of terahertz (far infrared wavelengths). It comprises a first optical source (2) emitting a first beam (FTHz) in said terahertz domain, a first semiconductor material plate (1) illuminated by said terahertz beam and a second optical source (3) emitting a second beam (FIR) at a wavelength enabling the first semiconductor material plate (1) to be saturated and rendered reflecting at the terahertz wavelength. The invention also concerns a system for measuring terahertz signals as well as a terahertz generator. The invention is applicable to systems for measuring terahertz signals and terahertz generators.

摘要： The invention concerns a detection system (7) for measuring at least one characteristic of an inked zone (5) comprising at least one sensor adapted to sense a light radiation reflected by said inked zone (5) and to generate a measurement signal representing at least the characteristic of the inked zone (5). Such a system further comprises at least one first optic fiber (10), adapted to convey up to the neighbourhood of the inked zone (5), a light radiation emitted by a light source (11).

摘要： The present invention relates to a system for generating wavelength-tunable, ultra-short light pulses within the visible or infrared light spectrum. According to the invention, said system includes an injection module (10) including a light source (9, 99) and a wavelength-tunable spectral filter (8). The light source (9, 99) is suitable for generating short light pulses (100), having a duration measured in nanoseconds, within an emission spectrum having a spectral width of several tens of nanometers to several hundred nanometers. The spectral filter (8) has a spectral width between 250 pm and 3 nm and is suitable for spectrally and temporally filtering said short light pulses (100) such that the injection module (10) generates wavelength-tunable, spectrally filtered, ultra-short light pulses (110). Said system also includes at least one optical amplifier (20, 30) suitable for generating wavelength-tunable, ultra-short, amplified pulses (120, 130) based on the wavelength of the spectral filter (8).
