FIG. 1.

(a) Schematic of experimental setup in studying random lasing and accompanying weak localization of light in a Nd doped phosphate glass cube; (b)shows a photograph taken from the top view of the lasing glass cube; (c) random laser emission at multiple wavelengths versus pumping power (the inset depicts the nonlinearity at 535 nm in a smaller scale).

Image of FIG. 2.
FIG. 2.

(a) Laser emission spectra obtained at detection angle θ = 30° under different pumping powers; (b) measured angular emission distribution of the yellow light peaked at 596 nm from the Nd+3 doped phosphate glass cube in its random lasing mode; (c) configuration of Nd+3 doped phosphate glass unit; (d)sketch representing the scattering in the Nd+3 doped phosphate glass cube.

Image of FIG. 3.
FIG. 3.

(a) A typical dynamics of fading-off of the lasing emission upon turning off the pumping light; (b) is a micrograph taken with an atomic force microscope; (c) intensity dynamics of the reflective and transmitted laser beams passing through the illuminated zone during turning on/off pumping light (to see the two lines clearly, the reflective curve was shifted up 0.3 units; a break is inserted in the graph to show the turning on/off processes in more details).

Image of FIG. 4.
FIG. 4.

A typical dynamics of the lasing emission at 1062 nm for a pulsed mode pumping diode laser at 804 nm.
