Submicron single-shot ablation features produced by femtosecond laser pulses was investigated in silicon-on insulator with atomic force microscopy. The results are fitted with a model that includes secondary absorption in the laser-induced plasma.

We have investigated the influence of Nd: YAG laser light at 1064 nm on the growth and erasure of x (2) gratings using 790/ 395-nm light in Tm-doped fibers. The addition of 1064-nm light to the writing pair of 790/395 nm was observed to cause at most

Since the first experiments on femtosecond laser waveguide writing the question on which mechanisms are responsible for the refractive index change immediately arose. Several efforts have been made in that direction but no conclusive answer has been

Femtosecond laser writing was used to fabricate waveguides in undoped and rare-earth doped polyphosphate glasses. The influence of glass composition and laser parameters on waveguide properties and structural changes in the glass will be discussed.

Laser tweezers Raman spectroscopy (LTRS) was used to acquire the Raman spectra of leukemic T lymphocytes exposed to the chemotherapy drug doxorubicin at different time points over 72 hours. Changes observed in the Raman spectra were dependent on drug

We report a 10(3) increase in efficiency of second-harmonic generation in Tm(3+)-doped aluminosilicate glass fibers when the wavelength of the fundamental beam is tuned to the maximum of the (3)H(6) ? (3)F(4) absorption of Tm(3+) at 785 nm. This resu

We study saturation of photoinduced second-harmonic generation in a Ge-doped silica fiber by modulating the relative phase between the fundamental and second-harmonic writing beams. We shift the phase by pi and present measurements that identify satu
