The results will be shown in the last part of the book. Remotely sensing fluorescence from the fragments of chemical and biological agents in all forms, gaseous, aerosol or solid, inside the filaments in air is demonstrated in the laboratory. We shall describe the generation of pulses at other wavelengths in the visible and ultraviolet (UV) starting from the near infrared pump pulse at 800 nm through four-wave-mixing and third harmonic generation, all in gases. We call this filamentation nonlinear optics. Because the intensity inside the filament core is high, new ways of doing nonlinear optics inside the filament become possible. Long range propagation at high intensity, which is seemingly against the law of diffraction, is probably one of the most exciting consequences of this new subfield of nonlinear optics. Thus, new phenomena are observed, such as long range filamentation, intensity clamping, white light laser pulse, self-spatial filtering, self-group phase locking, self-pulse compression, clean nonlinear fluorescence, and so on. Although self-focusing is an old subject of nonlinear optics, the consequence of self-focusing of intense femtosecond laser pulses is totally new and unexpected. This book attempts to give a discussion of the physics and current and potential applications of the self-focusing of an intense femtosecond laser pulse in a transparent medium.
