The femtosecond laser-induced fiber Bragg grating is an effective sensor technology that
can be deployed in harsh environments. Depending on the optical fiber chosen and the …

Silica glass is a high-performance material used in many applications such as lenses,
glassware, and fibers. However, modern additive manufacturing of micro-scale silica glass …

We examined the physical chemistry underlying a wet chemical etching-assisted
femtosecond laser microfabrication technique. Close scrutiny of etching reagents and the …

Ultrashort laser pulses can modify the inner structure of fused silica, generating refractive
index changes varying from soft positive (type I) light guiding forms to negative (type II) …

We report an experimental investigation of fluorescence confocal microscopy as a tool to
measure subsurface damage on grinded fused silica optics. Confocal fluorescence …

The material response following nanosecond, UV laser induced breakdown inside of the exit
surface of fused silica is investigated using multimodal time resolved microscopy. The study …

High peak power laser systems are vulnerable to performance degradation due to
particulate contamination on optical surfaces. In this work, we show using model …

The technique of femtosecond laser-induced inscription of fiber Bragg gratings creates a
structure in the optical fiber that can be used effectively as a sensor especially when …

Growth of laser damage on fused silica optical components depends on several key
parameters including laser fluence, wavelength, pulse duration, and site size. Here we …

Low energy femtosecond laser pulses locally increase the refractive index and the hydro-
fluoric acid etching rate of fused silica. These phenomena form the basis of a direct-write …
