The concept of random lasers exploiting multiple scattering of photons in an amplifying
disordered medium in order to generate coherent light without a traditional laser resonator …

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 …

The point-by-point technique of fabricating fibre-Bragg gratings using an ultrafast laser
enables complete control of the position of each index modification that comprises the …

Femtosecond (fs) laser pulses direct writing technology has been extensively employed to
achieve microfabrication in various optical fibers for a broad range of applications. In this …

The use of ultrashort laser pulses for fiber grating inscription has many advantages in
comparison to continuous wave and long pulse lasers. The most important one is that it …

Diamond has attracted great interest in the quantum optics community thanks to its nitrogen
vacancy (NV) center, a naturally occurring impurity that is responsible for the pink coloration …

Since its demonstration in 2003, Bragg grating inscription with high-power femtosecond
pulse duration infrared sources and phase masks has proven to be an effective and far more …

We report the inscription of low-loss fiber Bragg gratings using focused femtosecond (fs)
pulses and a continuous core-scanning technique. This direct-write technique produces …

We demonstrated a linear-cavity fiber laser using a fiber Bragg grating (FBG) fabricated by
femtosecond laser and a Sagnac loop as cavity mirrors. The temperature sensing response …

Instead of the evanescent field sensors, an oscillating wave sensor based on the Goos–
Hänchen effect is proposed in this letter. It is demonstrated that as the intrinsic dam** is …
