Laser Cleaning/Ablation Webinar
05/23/2018 14:00 to 05/23/2018 15:00 (America/Montreal)
Rez Mani did an M.Eng in Engineering Physics focused on optical properties of semiconductors from McMaster University in Hamilton, Ontario. This followed by a Ph.D. in Earth and Space Science focused on satellite optical instrumentation from York University in Toronto, Ontario. After working in the industry for 10 years where he participated in a multitude of optical/laser/spectroscopic projects, he returned to York University as a contract faculty and a research associate in 2011. He has also worked for Allied Scientific Pro as a consultant since 2011 and as an application scientist since 2017.
Space-born instruments carry many electronic devices including micro-processors, shift registers, op-amps, flip flops, etc. If a charged particle or an uncharged particle from space, strikes a sensitive node of an electronic circuit, it may cause a disruption or permanent damage. Testing of electronic circuits prior to space launch for radiation hardness is crucial to protect the electronic devices against this danger. Although testing in particle accelerator facilities produces absolute results for dosage of damage threshold, the process is expensive and can be done only in very localized test centers. The optical testing using near IR pulsed lasers using femto/pico-second pulse width and pico/nano joule pulse energy is much easier to set up and can be done at any location. The laser technique can focus on the device with submicron resolution. The optical method is unable to measure the absolute upset threshold but the laser upset threshold can be compared with the ion beam upset threshold. It is assumed that the relative differences remain the same throughout the measurements and hence all subsequent measurements can be done with the pulsed laser. Although the pulsed-laser method is compared to the radiation method, it is necessary to emphasize that it is not meant to replace it. Instead, the pulsed laser method is meant to be complementary to the radiation method.

Host: Rez Mani did his PhD from York University in 2001 in satellite spectroscopic instrumentation. He worked in the industry for nearly 9 years, during which he participated in many optical, laser and spectroscopic projects where he used many different types of high power lasers such as Nd:YAG, CO2 and Ti:Sapphire. He returned to York University in 2011 as a researcher and a contract faculty. He currently teaches the course "Atmospheric Pollution" for the department of Natural Science at York University. He has also been collaborating with Allied Scientific Pro as a consultant for more than 6 years.
