Research News
Light Regulated Soliton Dynamics in Liquid Crystals
Electrically powered solitons are particle-like field configurations in out-of-equilibrium nematics. The authors present a reconfigurable optoelectronic approach capable of regulating the entire lifecycle of solitons by utilizing multi-strategy digital light projection to construct delicate patterning of virtual electrode. The optical power densities of the light patterns were measured using an Ophir Nova power meter connected to an Ophir PD300-UV probe. Soliton Dynamics.
Thermal Disorder Prevents Suppression of Ultra-Fast Photochemistry
Strong coupling between molecules and confined light modes of optical cavities to form polaritons can alter photochemistry. The authors combine simulations and experiments to show that for an ultra-fast photochemical reaction such thermal disorder prevents the modification of the potential energy surface and that suppression is due to radiative decay of the lossy cavity modes. The collected emission intensity was normalized by the sum of the energies of all excitation pulses, which were recorded pulse by pulse with an Ophir PD10-C sensor. Ultra-Fast Photochemistry.
Frequently Asked Questions
Q: I have found some old Ophir/Spiricon/Photon equipment in my lab. Can I get help getting it working again?
A: Yes, we will do what we can to assist you. Please contact our Product Support Department at service.ophir.usa@mksinst.com or by phone at 1-800-383-0814.
Q: When I run BeamGage with my beam profiling camera, it is prompting for a license key. Where can I find it?
A: Ophir-Spiricon beam profiling cameras can be licensed for individual software operation. Older beam profiling cameras may not be licensed for BeamGage. If you provide us with the serial number of the camera we can confirm its licensing. Upgrades to BeamGage software can be purchased. We do recommend that old, discontinued camera models that can no longer be repaired be replaced with current models that are fully supported.
