Effect of experimental parameters on optimal reflection of light from opaque media
Benjamin R. Anderson, Ray Gunawidjaja, Hergen Eilers
Previously we considered the effect of experimental parameters on optimized transmission through opaque media using spatial light modulator (SLM)-based wavefront shaping. In this s…
Random Lasing and Reversible Photodegradation in Disperse Orange 11 Dye-Doped PMMA with Dispersed ZrO Nanoparticles
Benjamin R. Anderson, Ray Gunawidjaja, Hergen Eilers
We report the observation of intensity feedback random lasing at 645 nm in Disperse Orange 11 dye-doped PMMA (DO11/PMMA) with dispersed ZrO nanoparticles (NPs). The lasing thre…
Photodegradation and self-healing in a Rhodamine 6G dye and YO nanoparticle-doped polyurethane random laser
Benjamin R. Anderson, Ray Gunawidjaja, Hergen Eilers
One of the fundamental difficulties in implementing organic dyes in random lasers is irreversible photodegradation of the dye molecules, leading to loss of performance and the need…
Stability of optimal-wave-front-sample coupling under sample translation and rotation
Benjamin R. Anderson, Ray Gunawidjaja, Hergen Eilers
The method of wavefront shaping to control optical properties of opaque media is a promising technique for authentication applications. One of the main challenges of this technique…
Low-Threshold and Narrow Linewidth Diffusive Random Lasing in Rhodamine 6G Dye-Doped Polyurethane with Dispersed ZrO Nanoparticles
Benjamin R. Anderson, Ray Gunawidjaja, Hergen Eilers
We report on low-threshold and narrow linewidth intensity feedback random lasing in Rhodamine 6G dye-doped polyurethane with dispersed ZrO nanoparticles. Depending on the dye/p…
Microgenetic optimization algorithm for optimal wavefront shaping
Benjamin R. Anderson, Patrick Price, Ray Gunawidjaja +1
One of the main limitations of utilizing optimal wavefront shaping in imaging and authentication applications is the slow speed of the optimization algorithms currently being used.…
