Raman, 27Al and 29Si NMR spectroscopies are used to investigate the structure of [0.15Na2O–0.12MgO–0.03Al2O3–0.70SiO2](100−x): [Eu2O3]x glasses with varying Eu2O3 content (x=0, 0.73, 1.26, 3.90, 5.26 and 8.11 mol%). Spectral changes in the Ra

We report a systematic study of a grating formation in which the [Eu2O3] in sodium–magnesium–aluminosilicate glasses is varied from 0.76 to 8.11 mol %. The growth, decay, and erasure of the grating are reported as functions of the [Eu2O3]. The ma

We demonstrate that strong, persistent refractive index gratings can be formed and erased using off-resonance excitation in Eu3+-doped alkali silicate glass. The signal build-up time and the erasing results show that the grating growth and decay are

We have studied the formation of laser induced permanent and transient refractive index gratings in Eu 3+ -doped dual alkaline earth silicate glasses. The growth, decay, and erasure of the grating are reported as functions of the write-beam power and

We measured the two-photon absorption (TPA) coefficient at the fundamental of a nanosecond pulsed Nd:YAG laser in Eu3+ -doped silicate glass using the intensity scan technique. The TPA coefficient was found to be 5.5cm/GW.

Laser-induced fluorescence from feline tissue injected with meta-tetra(hydroxyphenyl) chlorin (mTHPC, Foscan®) was measured to determine the relative drug concentration in the five tissues (kidney, liver, lung, nasal planum and thyroid). Seventeen a
