Studies of selective ablation off different thin film by ultrafast lasers were performed during this secondment. Laser tests and characterization analysis were done on a wide range of materials of interest in industry.
During November and December several secondments took place.
First, Helios Chan (M-solv HK) spent a month at NCLA. During his visit Helios had a chance to investigate interaction of ps laser pulses with different stacks materials of interest to advance packaging applications.
During his secondment at M-solv UK, Cormac had a chance to study and compare how process parameters for ablation of thin films depend on pulse duration and laser wavelength.
He got a chance to use new generation of programmable laser fiber sources.
The measurements during processing of selective ablation constituted first step for development of on line monitoring systems.
Improvments of process windows for complicate laser material interaction is not possible without a deep theoretical understanding and modeling. During Gerard's visit to M-solv deep insight into laser-material interaction of thin films on glass was approached taking in account optical and electronic properties of materials before and during an interaction with laser.
