Optical modes that carry orbital angular momentum (OAM) are routinely produced external
to the laser cavity and have found a variety of applications, thus increasing the demand for …

Laguerre–Gaussian (LG) beams are typical vortex beams with orbital angular momentum
(OAM), spiral wavefront phase, and donut-shaped intensity distribution. They are widely …

Active control of the spatial pump profile is proposed to exercise control over random laser
emission. We demonstrate numerically the selection of any desired lasing mode from the …

In this paper we demonstrate experimentally the intra-cavity generation of a coherent
superposition of Laguerre–Gaussian modes of zero radial order but opposite azimuthal …

Polariton condensates are macroscopic quantum states formed by half-matter half-light
quasiparticles, thus connecting the phenomena of atomic Bose–Einstein condensation …

We demonstrate lasing mode selection in nearly circular semiconductor microdisks by
shaping the spatial profile of optical pump. Despite of strong mode overlap, adaptive …

Over the last twenty years, diode pumping of solid-state lasers has opened new prospects
for the mode control and formation of Laguerre-Gaussian (LG) beams, enabling a large …

In this paper we experimentally demonstrate the intracavity generation of selected Laguerre–
Gaussian modes of variable radial order, from 0 to 5. Our technique requires only an …

The goal and essential parameter of laser light conversion is achieving emitted radiation of
higher brightness. For many applications, the laser beam must have the highest available …

We demonstrate an effective control of nonlinear interactions of lasing modes in a
semiconductor microdisk cavity by shaping the pump profile. A target mode is selected at the …
