High-efficiency supercontinuum generation in solid thin plates at 0.1 TW level.

چکیده
Supercontinuum generation in a solid-state medium was investigated experimentally. A continuum covering 460 to 950 nm was obtained when 0.8 mJ/30 fs Ti:sapphire laser pulses were applied to seven thin fused silica plates at a 1 kHz repetition rate. The primary processes responsible for spectral broadening were self-phase modulation (SPM) and self-steepening, while SPM and self-focusing were balanced to optimize the spectral broadening and suppress the multiphoton process. The output was compressed to a 5.4 fs and a 0.68 mJ pulse, corresponding to two optical cycles and 0.13 TW of peak power.

In this paper, we report the numerical analysis of a photonic crystal fiber (PCF) for generating an efficient supercontinuum medium. For our computational studies, the core of the proposed structure is made up of As2Se3 and the cladding structure consists of an inner ring of holes made up As2Se3 and four outer rings of air holes in MgF2. The proposed structure provides excellent nonlinear coeff...
متن کاملNumerical aperture dependence of damage and supercontinuum generation from femtosecond laser pulses in bulk fused silica
Competing nonlinear optical effects are involved in the interaction of femtosecond laser pulses with transparent dielectrics: supercontinuum generation and multiphoton-induced bulk damage. We measured the threshold energy for supercontinuum generation and bulk damage in fused silica using numerical apertures (NAs) ranging from 0.01 to 0.65. The threshold for supercontinuum generation exhibits a...

In our neutron generation experiment, high-energy deuterons were generated from coulomb explosion of CD solidnanoparticles and neutrons were generated by DD fusion reac...
متن کاملHigh-harmonic generation by field enhanced femtosecond pulses in metal-sapphire nanostructure
Plasmonic high-harmonic generation (HHG) drew attention as a means of producing coherent extreme ultraviolet (EUV) radiation by taking advantage of field enhancement occurring in metallic nanostructures. Here a metal-sapphire nanostructure is devised to provide a solid tip as the HHG emitter, replacing commonly used gaseous atoms. The fabricated solid tip is made of monocrystalline sapphire sur...
