Triple-Wavelength Thulium-Doped Fiber Random Laser Based on Random Fiber Grating
Photonics, 2023 We demonstrate a triple-wavelength thulium-doped fiber random laser using a 10 cm long random fiber grating to provide random distributed feedback and a superimposed fiber Bragg grating as the wavelength-selective mirror.

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.

Optofluidic Distributed Feedback Dye Lasers [PDF]
IEEE Journal of Selected Topics in Quantum Electronics, 2007 We review our recent work on poly(dimethylsiloxane) (PDMS)-based optofluidic dye lasers using a guided wave distributed feedback (DFB) cavity. We show experimental results of single-mode operation, an integrated laser array, multiple color dye lasing, mechanical and fluidic tuning, and monolithic integration with microfluidic circuits.
