The role of silver in the radiophotoluminescent properties in silver-activated phosphate glass and sodium chloride crystal

“…For example, fabrication and integration of three-dimensional (3-D) microstructures for lab-on-a-chip applications have been extensively demonstrated in FOTURAN TM , a commercially photosensitive glass [15,[18][19][20], using fs laser direct writing followed by thermal treatment and successive wet etching. More recently, intense fs laser pulses with high peak power densities (~100 TWcm -2 ) and high repetition rates (>200 kHz)…”

Tailoring light pulse amplitudes for optimal laser processing and material modification

“…By acquiring an understanding concerning the basic photoexcitation mechanisms, we will ultimately be able to develop and model the appropriate material-specific pulse-scripts. In a series of prior experiments, we have investigated the photophysical processes that occur in a commercially available photo-structurable glass ceramic material known as Foturan [10][11][12][13][14][15]. Specifically, we have measured the relationship between the incident laser irradiance (mW/mm 2 ) that is required for exposure and the resulting chemical solubility of the processed material following thermal treatment [12,14,15].…”

“…Specifically, we have measured the relationship between the incident laser irradiance (mW/mm 2 ) that is required for exposure and the resulting chemical solubility of the processed material following thermal treatment [12,14,15]. We have also measured laser-induced changes in the optical absorption properties (from the UV to the IR) of Foturan at different stages in the thermal transformation process [10,11,14]. In the initial application of the pulse-script patterning technique, we are exploring the controlled alteration of phase transformation processes in Foturan during directwrite patterning.…”
