Title: Self-formation of quasiperiodic void structure in CaF{sub 2} induced by femtosecond laser irradiation

Abstract

We report the self-formation of quasiperiodic void structure with the length of several hundred micrometers inside the CaF{sub 2} crystal. The quasiperiodical voids along the propagation direction of the laser beam were formed spontaneously after the irradiation of a single femtosecond laser beam which was focused at a fixed point inside the crystal sample. The length of the void array varied with the focal depth beneath the sample surface. The possible mechanism of the self-formed void structure was discussed.

  • The damage in fused silica and CaF{sub 2} crystals induced by wavelength tunable femtosecond lasers is studied. The threshold fluence is observed to increase rapidly with laser wavelength {lambda} in the region of 250-800 nm, while it is nearly a constant for 800<{lambda}<2000 nm. The ultrafast electronic excitation is also studied by a pump and probe method. The reflectivity increases rapidly in the latter half of pump pulse, which supports that impact ionization plays an important role in the generation of conduction band electrons (CBEs). We study the CBEs absorption via subconduction-band (sub-CB) transition, and develop a coupled avalanche model.more » Our results indicate that the CBEs absorption via sub-CB transition plays an important role in the damage in dielectrics irradiated by the visible and near ultraviolet femtosecond lasers. Our theory explains well the experiments.« less
  • Single crystal calcium fluoride (CaF{sub 2}) is an important material for vacuum-ultraviolet optical components. Unfortunately, all metal halides tend to form defects when exposed to energetic particles and laser radiation, and these defects can degrade optical performance. Here we examine the consequences of exposing CaF{sub 2} to 157 nm excimer laser radiation and show that several tens of thousands of pulses at fluences near 1 J/cm{sup 2} can color the material. Absorption spectra of the exposed material confirm the formation of metallic calcium nanoparticles similar to those produced by other forms of energetic radiation. The rate of nanoparticle formation dependsmore » on the bulk temperature and displays a local maximum near 50 deg. C. Absorption measurements at 157 nm display a transient absorption component that grows during prolonged irradiation and disappears on time scales of several minutes after irradiation ceases. The implications of these effects in optical components are discussed.« less
  • A new ultraviolet-irradiation--induced ordered structure is observed for CaF/sub 2//Si(111) by angle-resolved photoelectron spectroscopy. The new structure can be viewed as an ordered array of surface F centers and is characterized by a half-filled band extending 0.5 eV below the Fermi level.
  • We used femtosecond laser irradiation of titanium metal in an oxidizing environment to form a highly stable surface layer of nanostructured amorphous titanium dioxide (TiO{sub 2}). We studied the influence of atmospheric composition on these surface structures and found that gas composition and pressure affect the chemical composition of the surface layer but not the surface morphology. Incorporation of nitrogen is only possible when no oxygen is present in the surrounding atmosphere.
