Photosensitivity in Ge-doped silica optical waveguides and fibers with 193-nm light from an ArF excimer laser.
Photosensitivity in optical fibers and waveguides has been associated with the bleaching of an absorption band located near 5.0 eV (or 242 nm). We present new results for Bragg grating formation and UV bleaching experiments carried out using 193-nm light from an ArF excimer laser instead of the usual laser sources operating near 242 or 248 nm.
متن کاملTunable ArF excimer-laser source.
A tunable ArF* (193-nm) excimer source is described that produces over 125 mJ/pulse (peak) at 10 pulses/sec. This device has a spectral width of less than 2 cm(-1) and a demonstrated tunability of nearly 320 cm(-1) from 192.8 to 193.9 nm. Tunability, bandwidth, and mode control are achieved by injecting the fourth anti-Stokes line (in H(2)) of a frequency-doubled dye laser into an ArF* excimer-...
متن کاملArF Excimer Laser Annealing of Polycrystalline Silicon Thin Film
Crystallization of amorphous silicon (a-Si) using excimer laser annealing (ELA) has been reported since 1994 by Watanabe group. It is known as the best method to fabricate a good poly-silicon because it can heat the film up to the melting point and, at the same time no thermal damage occur into the glass substrate (Carluccio et al., 1997; Matsumura and Oh, 1999). ELA technique is widely used to...
متن کاملEffect of the ArF excimer laser on human enamel.
Human enamel surface was irradiated with ArF excimer laser and examined under light microscopy and scanning electron microscopy (SEM). Enamel surface was irradiated at three different areas with different energy fluences. It is demonstrated that the ArF excimer laser causes ablation of the calcified hard enamel tissue. Ablation curves were measured. There was no significant difference found in ...
متن کاملHIGH TEMPERATURE ABSORPTION COEFFICIENTS OF 02, NH3, AND H20 FOR BROADBAND ArF EXCIMER LASER RADIATION
-Experimentally-determined absorption coefficients for broadband ArF exclmer ra&atlon at 193 mm are presented at temperatures up to 3500 K for 02, NH3, and H20. These values were determined in a high-purity shock tube, either by measuring excimer pulse fractional absorptions or by measuring photolysls-product yields. Correlations between absorption coefficients and wbratlonal populations of the...
