Fiber Bragg grating (FBG) is the most widely used optical fiber sensor due to its compact
size, high sensitivity, and easiness for multiplexing. Conventional FBGs fabricated by using …

The rapid expansion of femtosecond (fs) laser technology brought previously unavailable
capabilities to laser material processing. One of the areas which benefited the most due to …

In this article, we review recent advances in the technology of writing fiber Bragg gratings
(FBGs) in selected cores of multicore fibers (MCFs) by using femtosecond laser pulses. The …

This work proposes the quasi-distributed real-time monitoring and control of laser ablation
(LA) of liver tissue. To confine the thermal damage, a pre-planning stage of the control …

The paper presents a novel three-dimensional quasi-continuous shape sensor based on an
FBG array inscribed by femtosecond laser pulses into a 7-core optical fiber with a polyimide …

A compact random fiber laser based on a short artificial Rayleigh reflector and heavily-
doped Er fibers (custom-made and commercial as a reference) has been proposed …

In this article, we propose a temperature-based proportional–integral–derivative (PID)
controlling algorithm using highly dense fiber Bragg grating (FBG) arrays for laser ablation …

A multicore fiber Bragg grating (MC-FBG) array shape sensor is a powerful tool for a variety
of applications. However, the efficient fabrication of high-quality MC-FBG arrays remains a …

Long dynamic population gratings (DPGs) formed in rare-earth-doped fibers have unique
spectral characteristics compared to other types of fiber gratings, making them suitable for …

Laser ablation (LA) of cancer is a minimally invasive technique based on targeted heat
release. Controlling tissue temperature during LA is crucial to achieve the desired …
