Over the past two decades, many different types of extremely fast phenomena have been successfully studied by means of femtosecond time-resolved optical spectroscopy. Time-resolved electron-temperature measurement in a highly excited gold target using femtosecond thermionic emission. Second harmonic generation in plasmas produced by intense femtosecond laser pulses. The advent of super-intense femtosecond lasers has made possible charged par ticle acceleration schemes proposed in the early 1980s. The femtosecond laser is used only in order to achieve appropriate initial conditions. The results further indicate that thermal effect is important in femtosecond laser processing. On the interaction of femtosecond laser pulses with cluster targets. Explosion of atomic clusters heated by high-intensity femtosecond laser pulses. For femtosecond pulses, the crater profiles were without convexity formation. The best ablation efficiency was observed with femtosecond laser pulses. Energetic electrons emitted from ethanol droplets irradiated by femtosecond laser pulses. Such a large value of energy can definitely not be possible with cavity dumped oscillators, especially delivering pulses of 10- 20 femtosecond (fs). Complete characterization of damage threshold in titanium doped sapphire crystals with nanosecond, picosecond, and femtosecond laser pulses. In addition, the rapidly ionizing high-density medium modifies the temporal structure of femtosecond laser pulse due to self-phase modulation. Details of great interest were observed for the first time with high quality femtosecond 90-degree interferometry. Such experimental investigations have shown that, after the femtosecond laser pulse excitation, the electron distribution is far from equilibrium. Angular dispersion and temporal change of femtosecond pulses from misaligned pulse compressors. However, the use of femtosecond laser pulses for plasma generation has opened up a wealth of interesting new possibilities and applications. |
