“…In the last decade, fabrication of three-dimensional (3D) microstructures inside the transparent materials using ultrashort laser pulses encountered a significant progress in fundamental and applied science, opening up new paths in a vast range of applications [1][2][3][4][5]. The implementation of such a fascinating tool made possible the fabrication of multilayered optofluidic elements [6][7][8], optical waveguides [9], 3D optical memory [10,11] and lab-on-a chip devices [12][13][14][15]. In particular, previous studies demonstrating fabrication of hollow microchannels inside the Foturan glass, type of photostructurable glass [16][17][18], ensured the possibility of using them as 3D microfluidics for cell biology [19].…”

Foturan glass is a photosensitive transparent material which has attracted much interest for microfluidic applications due to possibility of volume processing by ultrafast lasers. In this work, we have investigated the effect of picosecond laser on volume processing in Foturan glass when varying the beam diameter incident on a lens. To this end, specific laser focusing configurations have been designed using raytracing models and an analysis protocol has been developed in the lens focusing region in order to describe the focal point displacement occurring at the variation of the incident laser beam diameter. The numerically simulated results were explained in association with Rayleigh length and found to be in good agreement with the experimental data obtained at well-defined conditions. Specifically, it was found that the hollow microstructures developed by thermal treatment and chemical etching after laser irradiation were significantly displaced along the propagation direction when the incident beam diameter varied in the range of 1-3.5 times. This approach aims to bring an essential contribution to the field of ultrashort pulse lasers micro and nanoprocessing in transparent materials proving that the laser beam focus position and its size can be precisely controlled with high precision by automated optics for the variation of incident laser beam diameter in predefined conditions. This approach has the potential for laser multi-beam processing at various volume depths using the same optics setup and may even be applicable to two-photon excitation microscopy.

“…Over the past several years, a great deal of work has been carried out in the development and characterization of a wide variety of optical glasses for different applications [1][2][3][4][5][6][7][8][9]. In recent years, a special interest has been focused towards the production of fluoro-borate glasses because of their potential applications as luminescent materials [10][11][12].…”

We report here the luminescence spectra of certain rare earth ions (Eu 3+ , Tb 3+ & Ho 3+ ) doped B 2 O 3 -BaO-LiF/AiF 3 based on the measurements of emission and decay curves of prominent emission transitions. For both the reference host glasses, FTIR, XRD, DTA-TG profiles have been recorded to understand their structural and thermal properties. Eu 3+ doped glasses have shown five emission transitions of 5 D 0 → 7 F 01,2,3 & 4 located at 580nm, 593nm, 615nm, 655nm and 704nm respectively with an excitation at λ exci = 392 nm ( 7 F 0 → 5 L 6 ). Also under an UV source, these europium glasses have displayed a bright red emission from their surfaces. Tb 3+ glasses have exhibited four emission bands of 5 D 4 → 7 F 6,5,4,3 at 491nm, 547nm, 588nm and 625nm respectively with an excitation at λ exci = 376 nm ( 7 F 6 → 5 G 6 ). Intense green emission from the glass surfaces has been noticed upon exposure to the UV source. Prominently bluish-green emission has been noticed from the surfaces of the holmium glasses under an UV source and same emission transition ( 5 F 4 → 5 I 8 ) at 519 nm with an excitation at λ exci = 389 nm ( 5 I 8 -5 G 4 ) has also been obtained from their measured emission spectra. For all the prominent emissions of the rare earth glasses, decay curves have been measured to compute their lifetimes.
