IRL: My journey in femto-second laser material interaction – The heat, the invisible and the slippery

Date: 25 Oct 2013 - 25 Oct 2013

Venue: SIMTech Auditorium, Tower Block, Level 3

SIMTech 20th Anniversary Seminar Series - Joint Lab Series Talk

This talk is designed to share the recently achieved outcome of SIMTech-NTU research collaborations on femtosecond laser material processing as well as to promote SIMTech-NTU joint-lab capabilities to the local industry partners, academic researchers and students.


3.00 pm    Registration

3.15 pm    Presentation by Professor Lam Yee Cheong

4.00 pm    Q&A

4.15 pm    A brief talk on SIMTech-NTU Joint-lab scholarships by RLO

4.30 pm    Networking & Posters

5.00 pm    End

Outcomes of research collaborations with SIMTech over the years in femto-second laser material interaction are presented. These include: (a) against the general belief at that time and with rather basic and simple equipment, significant heat conduction in femto-second laser ablation of materials was demonstrated; (b) “invisible” laser markings which could not be detected with established and sophisticated measurement techniques, but could be detected with a simple technique without the assistance of any equipment; (c) the controlled modification of water contact angle of a polymeric surface ranging from hydrophilic to hydrophobic; and (d) the laser activities of the recently established SIMTech-NTU Joint Laboratory (Precision Machining) will be introduced.

About the Speaker
Dr Lam Yee Cheong graduated in Mechanical Engineering, Melbourne University, Australia and was awarded the Dixon Scholarship for “Outstanding Academic Achievement”. Subsequently, he obtained his Ph.D. from the same University and was awarded the M.H. de Fina Memorial Prize for “The Best Postgraduate Student in the Department”.

Dr Lam is currently a Professor and Associate Chair (Research) in the School of Mechanical and Aerospace Engineering, Nanyang Technological University. Concurrently, Dr Lam is a faculty fellow of the Singapore-MIT-Alliance (SMA).  He had held joint appointment as Principal Scientist with the Singapore-Institute of Manufacturing Technology (SIMTech), and currently a Co-Director of the SIMTech-NTU Joint Lab (Precision Engineering) 

Before joining NTU, Dr Lam was a Reader with the Department of Mechanical Engineering, Monash University, Clayton Campus. He was the National President of the Australian Fracture Group and a Director of the Far East Oceanic Fracture Society. Professor Lam was Head (Monash Node) of the Co-operative Research Centre of Advanced Composite Structures (CRC-ACS), Australia, and its Program Coordinator for the Tooling and Repair Task. He was awarded a plaque by CRC-ACS “In Recognition of Service to CRC-ACS”.

He has been invited by the University of Melbourne, Australia to deliver the prestigious Tewksbury Lecture, and by Monash University, Australia to deliver the prestigious Harold Armstrong Memorial Lecture.

Who Should Attend
Researchers, industry partners from PE, aerospace, automotive and medtech industries, academic staff and students.
