Comprehensive Investigations on 1053 nm Random Distributed Feedback Fiber Laser

IEEE Photonics Journal, 2017
We design a 1053 nm Yb3+-doped random fiber laser (YRFL) based on the combination of Yb3+ -doped fiber (YDF) and single mode fiber (SMF), in which the YDF provides active gain, while SMF offers random distributed feedback.

Temporal ghost imaging with random fiber lasers

Optics Express, 2020
Ghost imaging in the time domain has opened up new possibilities to retrieve ultrafast waveforms. A pre-requisite to ghost imaging in the time domain is a light source with random temporal intensity fluctuations that are fully uncorrelated over the duration of the temporal waveform being imaged.

Randomly spaced chirped grating-based random fiber laser [PDF]

, 2018
A random fiber laser is demonstrated using a randomly spaced chirped-fiber Bragg grating (CFBG) array, which was fabricated along a 1-m-long erbium-doped fiber using a UV laser with a random separation ranging from 30 to 100 mm.
