Post-filament self-trapping of ultrashort laser pulses.
Laser filamentation is understood to be self-channeling of intense ultrashort laser pulses achieved when the self-focusing because of the Kerr nonlinearity is balanced by ionization-induced defocusing. Here, we show that, right behind the ionized region of a laser filament, ultrashort laser pulses can couple into a much longer light channel, where a stable self-guiding spatial mode is sustained...
متن کاملDevelopment of Ultrashort Pulsed VUV Laser and its Applications
Vacuum ultraviolet (VUV) laser systems for advanced applications such as micro and precise processing and photochemical reactions have been developed. We have been constructing a VUVMOPA system to generate output energy of sub-mJ with a pulse width of sub-picosecond at the wavelength of 126 nm. A VUV seed pulse, generated by the 7th harmonics of a 882 nm Ti:Sapphire (TiS) laser was amplified by...
متن کاملUltrashort pulsed fiber laser welding and sealing of transparent materials.
In this paper, methods of welding and sealing optically transparent materials using an ultrashort pulsed (USP) fiber laser are demonstrated which overcome the limit of small area welding of optical materials. First, the interaction of USP fiber laser radiation inside glass was studied and single line welding results with different laser parameters were investigated. Then multiline scanning was ...
متن کاملPathogen Reduction in Human Plasma Using an Ultrashort Pulsed Laser
Pathogen reduction is a viable approach to ensure the continued safety of the blood supply against emerging pathogens. However, the currently licensed pathogen reduction techniques are ineffective against non-enveloped viruses such as hepatitis A virus, and they introduce chemicals with concerns of side effects which prevent their widespread use. In this report, we demonstrate the inactivation ...
