1337 nm Emission of a Nd3+-Doped TZA Glass Random Laser [PDF]
Nanomaterials, 2023 Random lasers have been studied using many materials, but only a couple have used glass matrices. Here, we present a study of zinc tellurite and aluminum oxide doped with different percentages of neodymium oxide (4 wt.%, 8 wt.%, and 16 wt.%) and ...

A fractional diffusion random laser. [PDF]
Sci Rep, 2019 AbstractThe goal of this letter is to introduce the concept of a non-resonant fractional random laser. This is achieved by extending the classical Letokhov model of photon diffusion through disordered gain media to fractional differential operators in space and time.

Internal modulation of a random fiber laser [PDF]
Optics Letters, 2013 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.
