 The PSU Physics Department will be holding our 1st seminar for the Winter 2020 series this Monday, January 13th, 2020. 
Our guest speaker will be Michaela Kleinert from Willamette University.
Date: Monday, January 13th
Location: SB1-107 at 3:15pm
Topic:  "Do not look into the laser beam with your remaining eye!" - Laser ablation, hydrophobic surfaces, and nanoparticles at Willamette University
(Refreshments will be served as usual!)
Since its invention in 1960, the laser has become an integral part of our society. While most everyday lasers are continuous wave lasers of low power – for example barcode scanners at the grocery checkout –, powerful pulsed lasers that produce extremely short bursts of light find more specialized applications both in research and industry. From the creation of super-hydrophobic surfaces that are completely water-repellent to the formation of micrometer sized structures that guide light or allow computers to work properly, from identifying explosives at long range to determine the chemical composition of ancient coins or even rocks on Mars – if you can imagine it, there is a laser to do the job!  A generous donation of two picosecond pulsed laser systems by ESI (a division of MKS) has allowed me to enter this fascinating field of research. In this talk I will present projects that are currently being investigated in my lab: The formation of nanoparticles using pulsed laser ablation in liquids, the creation of hydrophobic surfaces using pulsed laser ablation in various gas environments, and the texturing of titanium surfaces to improve cell adhesion for medical implants.
