Technology Lecture: Picosecond Fibre Laser - A New Industrial Tool
Date: 07 May 2008 - 07 May 2008
Venue: SIMTech Training Room, Tower Block, Level 3
Micro manufacturing processes are the fastest growing area of applications for lasers due to the dynamic consumer electronics market. For example, the booming photo-voltaic industry has boosted the demand for laser micro-processing applications and alternative manufacturing technologies which can lower the initial high investment cost.
Lasers have the potential to overcome some of the difficulties introduced by traditional tools because of lower investment cost, no mechanical stress to the workpiece and no chemicals involved. However, problems associated with conventional lasers such as large heat affected zones (HAZ) remain largely unsolved. The use of green or UV-lasers with optimised laser parameters can reduce this problem, but cannot be totally eliminated.
It has been demonstrated that with ultra short laser pulses, materials can be processed with excellent quality and high precision. However, slow processing speed and complexity in the system are the short comings with these lasers. Corelase has developed X-LASE picosecond fiber laser to overcome these problems. High processing quality combined with high processing speeds makes X-LASE a very attractive industrial tool.
