Technology Infusion Programme (TIP) course on Industrial Laser Processing

Date: 05 Oct 2005 - 16 Nov 2005

Venue: SIMTech, Seminar Room, Valley Block, Level 1

Course Introduction

The objective of the industrial laser processing course is to provide participants with the fundamentals and industrial applications of laser technology. As diode-pumped solid-state (DPSS) UV laser has recently emerged as a major tool in optoelectronics and semiconductors manufacturing, the course will cover areas of UV laser applications in additional to other laser technologies. The course will be delivered through the combination of classroom lectures (12 hrs) and lab demonstrations (6 hrs) in selected industrial applications.
