Internal modulation of a random fiber laser [PDF]
A characterization of a modulated random mirror laser has been experimentally carried out. Unlike conventional internally modulated fiber lasers, no distortion of the modulating frequency or self-mode-locking effects were measured. The behavior of the laser using pulsed and analog modulation up to 12 GHz is shown.

Random fiber Bragg grating Raman fiber laser
We demonstrate for the first time to our knowledge a Raman random fiber laser (RRFL) based on a long random fiber Bragg grating (RFBG-RRFL). Unlike other recently demonstrated random fiber lasers that rely on incoherent Rayleigh scattering feedback, the present scheme uses randomly distributed phase shifts inside a fiber-meter long Bragg grating as a ...

Spectrum-tailored random fiber laser towards ICF laser facility
Broadband low-coherence light is considered to be an effective way to suppress laser plasma instability. Recent studies have demonstrated the ability of low-coherence laser facilities to reduce back-scattering during beam–target coupling.

Advances in Random Fiber Lasers and Their Sensing Application
Compared with conventional laser, random laser (RL) has no resonant cavity, reducing the requirement of cavity design. In recent years, the random fiber laser (RFL), a novel kind of RL, has made great progress in theories and experiments.

Generation of Narrow Modes in Random Raman Fiber Laser Based on Multimode Fiber
We present a new design of a random Raman fiber laser based on a graded-index multimode fiber as the media composing the cavity that allows the generation of narrow spectral lines.

A random Q-switched fiber laser [PDF]
AbstractExtensive studies have been performed on random lasers in which multiple-scattering feedback is used to generate coherent emission. Q-switching and mode-locking are well-known routes for achieving high peak power output in conventional lasers.

Efficient 1054 nm Raman Random Fiber Laser
Low–coherence laser is regarded as the key to mitigating laser–plasma instability (LPI) in laser–driven inertial confinement fusion (ICF), where LPI can decrease the laser energy coupled to the target.
