This study introduces a compact, portable femtosecond fibre laser system optimized for synchronization with SPring‐8 synchrotron X‐ray pulses in a uniform filling mode, offering a practical and cost‐effective alternative to traditionally, fixed, installed laser systems for time‐resolved spectroscopy combining synchrotron X‐ray pulses and laser pulses ...

We propose and experimentally demonstrate a novel dual-polarization distributed feedback fiber laser (DFB-FL) sensor based on femtosecond laser-inscribed in-fiber stressors. The resonant cavity of the DFB-FL sensor consists of a phase-shifted fiber Bragg

Multistability manipulation by reinforcement learning algorithm inside mode‐locked fiber laser
Abstract Fiber mode‐locked lasers are nonlinear optical systems that provide ultrashort pulses at high repetition rates. However, adjusting the cavity parameters is often a challenging task due to the intrinsic multistability of a laser system. Depending on the adjustment of the cavity parameters, the optical output may vary significantly, including Q ...

In this paper, a conventional wavelength band (C-band) fiber laser with a tunable single-longitudinal-mode (SLM) output using multilayer graphene as a saturable absorber is demonstrated. The proposed fiber laser uses a short length of highly doped erbium-

Vector Dissipative Solitons in Graphene Mode Locked Fiber Lasers
Vector soliton operation of erbium-doped fiber lasers mode locked with atomic layer graphene was experimentally investigated. Either the polarization rotation or polarization locked vector dissipative solitons were experimentally obtained in a dispersion-

Dielectric‐Metasurface‐Enhanced Kerr Self‐Modulation for Passively Q‐Switching
By exploiting the enhanced Kerr effect from a periodic array of silicon nanodisks, the Mie resonance of the unit cells enhances is redshifted, achieving a novel transmission modulation for pulsed laser generation. And a stable Q‐switched pulse laser output with a duration of 1.4 µs and a repetition rate of 60 kHz is achieved.

Absolute calibration of fiber-coupled single-photon detector
We show a setup for characterising the efficiency of a single-photon-detector absolutely and with a precision better of 1%. Since the setup does not rely on calibrated devices and can be implemented with standard-optic components, it can be realised in ...
