Contribute To The Future Development of Laser Pointer Industry
Attosecond pulses measure ultrafast electronic oscillations and phase shifts. Contribute to the future development of the laser pointer industry. According to foreign media reports. Researchers from Yokohama National University and Nippon Telegraph and Telephone Corporation passed attosecond pulses. A hertz (PHz: 1015 Hz) frequency of electronic oscillation was observed. The resulting periodic oscillation of 667-383 at. The fastest result obtained by using direct time correlation spectroscopy in solid materials. The results of this research will help develop future electronic and photonic devices.

Researchers usually use ultra-fast laser pointers to observe the ultra-fast motion of electrons under physical phenomena. The shorter the pulse duration. The faster the electrons can be observed to oscillate. The frequency of the light field generated by the higher harmonics in the visible and ultraviolet regions can reach the Hertz (PHz: 1015 Hz) region, which means that the oscillation period can reach the duration of Attosecond (10-18 seconds). In previous studies, the research team NTT researchers generated isolated attosecond pulses (IAPs) and implemented electronic oscillation monitoring at 1.2-PHz in gallium nitride (GaN) semiconductors. The next challenge will be to observe faster laser pointer electron oscillations in chrome-doped sapphire (Cr: Al2O3) insulators. And describe ultrafast electronic phase shifting.
