Light pulses
WebSep 17, 2024 · Obtaining few-cycle pulses from industrial-grade lasers. The extremely short light pulses employed in attosecond-scale experiments consist of a single oscillation cycle of an electromagnetic wave. Such cycles are typically generated by propagating femtosecond (10 -15 s) laser pulses through tubes filled with noble gases such as argon … WebAbstract: This paper introduces and discusses the main aspects of ultrashort laser pulse filamentation in various transparent media such as air (gases), transparent solids and liquids. The properties of femtosecond filaments and their applications are presented.

Not only were they able to record these waves, but they also found the pulses can spontaneously speed up and slow down. Surprisingly, the waves even split into two separate pulses, moving at different speeds.
WebJul 1, 2024 · Although such toroidal light pulses (TLPs) travel at the speed of light, they are radically different from conventional plane electromagnetic waves on several counts: (1) TLPs possess non ... WebLight pulses as generated in mode-locked lasers can be extremely short, especially with passive mode locking. There is no universally accepted definition of “ultrashort”, but the term usually is applied to pulses whose pulse duration is at most a few tens of picoseconds, and often even in the range of femtoseconds.
