Spectrum shuttle technology: a new approach to generating and processing high-frequency pulses

In the world of science and technology, the generation and processing of high-frequency pulses are topics of great interest. Research team fromUniversity of Tokyo And theSaitama University Recently developed an innovative optical technology called “Spectrum Shuttle”. This technique allows the simultaneous production of high-frequency pulses and individual modification of their spatial features.

Spectrum shuttle method.

“Method” Spectrum shuttle » It involves scattering a very short pulse horizontally through diffraction gratings, and spatially separating the pulse into different wavelengths using parallel mirrors. These vertically aligned pulses undergo individual spatial modulation using a spatial light modulator.

The resulting modulated pulses, with varying time delays in the gigahertz range, produce pulses of high spectral redundancy, each with a unique spatial shape.

As stated in the magazine Association for Advanced Photonics,The proposed method succeeded in producing highly repeatable ,pulses with various wavelengths and time intervals separately. It has demonstrated the ability to modify spatial features, including positional shifts and peak splitting.

Potential applications

The method facilitates ultra-fast imaging on time scales A second again down to nanoseconds, allowing the analysis of rapid and non-repetitive phenomena. Its potential applications include detecting unknown ultrafast phenomena and monitoring rapid physical processes in industrial environments.

The ability to individually modulate pulses with high repeatability also offers interesting prospects in the field of microneedling and laser therapy.

It is worth noting that the compact design of the proposed method enhances its portability, making it applicable in various scientific research facilities and various industrial technology sectors.
