1. a kind of method for producing femtosecond Ultra-Violet Laser, including:

  • At first laser pulse steering to nonlinear optical crystal, first laser pulse has in the near-infrared part of electromagnetic spectrumIn fundamental wavelength, the first laser pulse have less than 1000 femtoseconds pulse duration;

    At least some photons from the first laser pulse are changed at the Part I of the nonlinear optical crystalInto the harmonic wavelength of the fundamental wavelength, to produce second laser pulse in the nonlinear optical crystal;

    At the Part II of the nonlinear optical crystal, the first laser pulse and the second laser pulse will be come fromAt least some photons be converted into the triple-frequency harmonics wavelength of the fundamental wavelength, to produce the 3rd in the nonlinear optical crystalLaser pulse;

    AndThe 3rd laser pulse is exported from the nonlinear optical crystal, wherein, the 3rd laser pulse has the arteries and veinsRush the duration.
