Characteristics of self-guided laser plasma channels generated by femtosecond laser pulses in air.
With ultrashort laser pulses (25 fs) and low energy (E=15 mJ), we observe laser plasma channels with a length over 5 m in air. The diameter of the plasma channel is measured to be 120 microm. The average electron density in the channel is inferred to be about 10(18) W/cm(3) with an interferometric method. At the same time, the temporal evolution of the electron density in the plasma channel is ...
متن کاملIon characteristics of laser-produced plasma using a pair of collinear femtosecond laser pulses
Femtosecond laser-pulse absorption is studied in silicon ablation plasmas by means of a pair of identical 10 W/cm collinear pulses separated on a picosecond time scale. The second laser-pulse modifies ionic characteristics of the preformed plasma, such as ion yield, ion energy, and average charge state. Resonance absorption is demonstrated to be the dominant mechanism by comparing results of s ...
متن کاملPaper airplane propelled by laser plasma channels generated by femtosecond laser pulses in air.
A long plasma channel, formed due to the dynamic balance between the nonlinear self-focusing and the plasma defocusing in the propagation of intense femtosecond laser pulses in air, is demonstrated to be able to continuously propel a paper airplane without complicated focusing optics. The maximum coupling coefficient generated by the plasma channel is found to be more than 8.5 dyne/W. In the pl...
متن کاملTwo-color photoemission produced by femtosecond laser pulses on copper
Single-color illumination of a copper surface by a red or an ultraviolet femtosecond laser pulse yields a threephoton (red) or a two-photon (UV) photoemission process. A multicolor, multiphoton process is generated when the red and the UV pulses overlap both in space and in time on the photocathode. It is shown that this emission process results from the absorption by an electron of one red and...
متن کاملQuasi-steady-state air plasma channel produced by a femtosecond laser pulse sequence
A long air plasma channel can be formed by filamentation of intense femtosecond laser pulses. However, the lifetime of the plasma channel produced by a single femtosecond laser pulse is too short (only a few nanoseconds) for many potential applications based on the conductivity of the plasma channel. Therefore, prolonging the lifetime of the plasma channel is one of the key challenges in the re...
