Optical Damage Threshold of Silicon for Ultrafast Infrared Pulses

While silicon has several properties making it an attractive material for structure-based laser-driven acceleration, its optical damage threshold, a key parameter for high-gradient acceleration, has been unknown. Here we present measurements of the optical damage threshold of crystalline silicon for ultrafast pulses in the mid-infrared. The wavelengths tested span a range from the telecommunica...

Mid-infrared ultrafast laser pulses induced third harmonic generation in nitrogen molecules on an excited state

We report on generation of third harmonic from nitrogen molecules on the excited state with a weak driver laser pulse at a mid-infrared wavelength. The excited nitrogen molecules are generated using a circularly polarized intense femtosecond pulse which produces energetic electrons by photoionization to realize collisional excitation of nitrogen molecules. Furthermore, since the third harmonic ...

320 fs Pulses from an Ultrafast Laser Inscribed Waveguide Laser Utilizing a Carbon Nanotube Saturable Absorber

We report the generation of sub-picosecond modelocked pulses from an ultrafast laser inscribed Er-doped waveguide laser. 320 fs pulses at a repetition rate of 40 MHz and energy of 31 pJ were facilitated via passive modelocking by a carbon nanotube saturable absorber.

Study of laser ablation using nano-second laser pulses

 In this paper, the laser ablation process based on the irradiation of nanosecond pulsed lasers on a copper target surface in the presence of Helium gas is studied. The dynamical behaviors of the generated plasma in the helium gas and evaporated copper at the atmospheric pressure are examined using a laser pulse, laser wavelength of and intensity of 7×1010W/cm2. A one-dimensional thermal model ...

Ultrafast dynamics and fragmentation of C60 in intense laser pulses

The radiation-induced fragmentation of the C60 fullerene was investigated by the tight-binding electron-ion dynamics simulations. In intense laser field, the breathing vibrational mode is much more strongly excited than the pentagonal-pinch mode. The fragmentation effect was found more remarkable at long wavelength λ≥800 nm rather than the resonant wavelengths due to the internal laser-induced ...
