Disclosed is a system for generating short or ultra-short light pulses, including a light source configured to emit temporally continuous-wave light radiation, an electrical generator configured to operate at a tunable frequency in a passband included between 5 and 100 GHz and to emit an analogue modulating electrical signal including at least one electrical pulse of duration included between 10 ps and 100 ps, and an electro-optical modulator having electrodes and an electrical passband that are suitable for receiving the analog modulating electrical signal, the electro-optical modulator being configured to optically amplitude modulate the continuous-wave light radiation depending of the analog modulating electrical signal and to generate modulated light radiation including at least one light pulse of duration included between 10 ps and 100 ps.

System for generating brief or ultra-brief light pulses

Disclosed is a system for generating wavelength-tunable, ultra-short light pulses within the visible or infrared light spectrum. The system includes an injection module including a light source and a wavelength-tunable spectral filter. The light source is suitable for generating short light pulses, 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 has a spectral width between 250 pm and 3 nm and is suitable for spectrally and temporally filtering the short light pulses such that the injection module generates wavelength-tunable, spectrally filtered, ultra-short light pulses. The system also includes at least one optical amplifier suitable for generating wavelength-tunable, ultra-short, amplified pulses based on the wavelength of the spectral filter.
