Host: Rez Mani did an M.Eng in Engineering Physics focused on optical properties of semiconductors from McMaster University in Hamilton, Ontario. This was 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. 

Webinar Description:   The webinar begins by explaining the fundamental differences between the near IR and mid-IR spectroscopy methods. The fundamental absorption bands exist in the mid-IR region, however overtones which are weaker can be found in the near IR region. Mid-IR instruments such as FTIR are expensive and bulky. Several industries are now turning to near IR spectroscopy for quality control since it is a fast and inexpensive method which uses light-weight portable spectrometers. NIR can be used to find the ingredients of food such as sugar, protein, moisture and fat, find ingredients of drugs, sort plastics for recycling, detect influenza virus in nasal fluid, detect Zika virus in mosquitoes, find polyester content of fabrics, and many other applications. Instead of using an array detector which is more expensive, a new method called Digital Light Processing (DLP) uses micro-mirrors to shine different parts of the spectrum one after another onto a single element detector and builds the spectrum. The technology and its applications are very promising. Use of chemometrics methods such as Partial Least Square (PLS) to make quantitative predictions is also discussed.

Title:  Laser cleaning principles and case studies

HostRez Mani did his M.Eng in Engineering Physics from McMaster University and his  PhD in satellite spectroscopic instrumentation from York University. He worked in the industry for nearly 9 years, during which he participated in many optical, laser and spectroscopic projects 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 and recently as an application scientist for more than a year.

Introduction:

The webinar gives an introduction to principles of laser ablation with particular emphasis on laser cleaning application. The pros and cons of using laser cleaning as compared to other cleaning methods are described. The parameters of importance as far as the laser and the materials to be worked on are considered. Finally, a few examples of laser cleaning are given including a video demonstration of the laser cleaning system by Allied Scientific Pro in a nuclear decontamination facility.

 

TOPICS: 

• Introduction to laser ablation
• Laser medium
• Types of lasers used in laser ablation
• Laser cleaning
• Other competing surface cleaning techniques
• Dependence of laser ablation on material properties and laser parameters
• Femto-second, Pico-second and Nano-second regimes
• Application of laser ablation          
              I. Case Study 1: Permafix nuclear decontamination facility testing in Richland, Wa, USA.
