Brightness enhancement in a solid-state laser by mode transformation

Author: Naidoo, Darryl ; Litvin, Ihar ; Forbes, A Date: Jul 2018 Laser brightness is a measure of the ability to deliver intense light to a target and encapsulates both the energy content and the beam quality. High-brightness lasers require that both parameters be maximized, yet standard laser cavities do ... Read more

Controllable beam shaping of coherent and incoherent beams by a laser amplifier

Author: Litvin, Ihar ; King, Gary R Date: Aug 2018 We propose the technique for a controllable manipulation of the transverse intensity distribution of an output beam by the temporal adjustment of a transverse gain profile in a laser amplifier. It was created by an independent manipulation ... Read more
Improving the laser brightness of a commercial laser system

Author: Naidoo, Darryl ; Litvin, Ihar ; Forbes, A Date: Feb 2017 We investigate the selection of a flat-top beam and a Gaussian beam inside a laser cavity on opposing mirrors. The concept is tested external to the laser cavity in a single pass and double pass regime where the latter mimics a single round ... Read more
Purity of vector vortex beams through a birefringent amplifier

Author: Sroor, H ; Lisa, Nyameko ; Naidoo, Darryl ; Litvin, Ihar ; Forbes, A Date: Apr 2018 Creating high-quality vector vortex (VV) beams is possible with a myriad of techniques at low power, and while a few studies have produced such beams at high power, none have considered the impact of amplification on the vector purity. Here ... Read more
Scalar and vector vortex beams from the source

Author: Naidoo, Darryl ; Roux, FS ; Dubery, Angela L ; Litvin, Ihar ; Piccirillo, B Date: Oct 2016 We introduce a laser for generating all states on the Higher-order Poincaré sphere by coupling spin angular momentum to orbital angular momentum and we demonstrate that the OAM degeneracy of a laser may be broken.

Shaping and detecting mid-IR light with a spatial light modulator

Author: Maweza, Elijah L ; Gailele, Lucas M ; Strauss, Hencharl J ; Litvin, Ihar ; Forbes, A ; Dudley, Angela L Date: Oct 2016 We demonstrate the operation and calibration of a spatial light modulator in the mid-IR region by creating and measuring the modal content and wavefront of structured light fields at 2um for the first time.
