PARTIALLY PUMPED RANDOM LASERS
International Journal of Modern Physics B, 2014Conventional lasers consist of two components: a gain material that is pumped in order to provide amplification of light and a cavity to provide feedback. Random lasers replace the traditional laser cavity with a random, multiple-scattering medium. This can give rise to complex lasing behavior, such as unpredictable multidirectional and multifrequency

Random-wavelength solid-state laser
Optics Letters, 2004The spectral properties of a diode-pumped Yb:Y2O3 ceramic laser are reported. We show experimentally that the instantaneous emission wavelengths of the laser change randomly with time, whereas its emission has fixed well-defined transverse modes. The central wavelength of the laser emission also shifts prominently with the increase of intracavity light

One essential component of a laser is the cavity, which provides optical confinement and feedback for lasing oscillation. In a highly disordered medium, light experiences multiple scattering and undergoes a random walk. Surprisingly, lasing can occur in a random system without well-defined cavities.

We demonstrate two-threshold random laser emission in the mixtures of GaAs powder with Al2O3 powder. The dilution of GaAs powder with Al2O3 powder helps to maximize the output efficiency of the stimulated emission.

The random distributed feedback (RDFB) fibre laser that provides stable, spatially incoherent continuous-wave lasing has been proved. It generates the distributed feedback fibre cavity which is formed by the Rayleigh backscattering in the fibre, and its gain is achieved by Raman amplification when the pump light enters into fibre, and its efficiency ...
