Center hosted another workshop on laser direct deposition on Nov. 10
at Purdue University.
About 35 people participated in the workshop. Please see the workshop page for details.
Center Industrial Advisory Board was held on Nov. 11 at Purdue
University. For details, please see
successful new results of several projects carried out at the Center
presented at two upcoming conferences.

Technology 2011 Conference & Exhibition during Oct,
16-20 in Columbus, Ohio and
International Congress on Applications of Lasers & Electro-Optics
(ICALEO) during Oct. 23-27 in Orlando, Florida.
recently established shadowgraphy and fluorescent measurement
set-up, we have been able to successfully capture the early plasma
formed during femtosecond laser ablation with picosecond time
resolution. For details, see the
new paper published in Physics of Plasmas. This study has
revealed new science on how early plasma affects laser-material
interaction in ultrashort laser ablation.
success story at the Center includes direct synthesis of Nitinol
shape memory alloy directly from elementary Ni and Ti powders.
An article summarizing this work is being published.
last few months, a number of industrial companies have visited the
Center, including Honda, Silfex, Deloro Stellite, Edison Welding
Institute, Strykers, Dow Chemicals, Lawrence Livermore Berkeley
National Lab, and Huffman. We welcome your visit anytime.
A new 1
kW fiber laser has been ordered from IPG Photonics. This new
laser will be used to outfit the existing 3 axis MAZAK milling
machine and will be utilized for projects dealing with
laser-assisted milling and laser welding.
powder feeder has been acquired and installed on the Optomec LENS750
system. The system now provides the capabilities of building
set-up for two-photon polymerization has been established. The
set-up includes a 3-axis nano positioning system from Aerotech, a
high NA objective lens and a Ti-Sapphire femtosecond laser.
This unit will be used to build 3D nano-size structures.

Industrial Laser Solutions published a featured article on Laser
Assisted Machining - LAM benefits a wide range of
difficult-to-machine materials, (pp.
18-22 in Jan/Feb 2011 issue). Industrial Laser Solutions is
one of the leading magazines dealing with laser applications to
manufacturing in industry.

Professors Shin and
Cheng jointly received a new NSF grant to focus on high speed
scribing of solar cell panels. This project will be carried
out in collaboration with industry and a national lab.
Professor Shin in
teaming with Prof. Jian Cao at Northwestern organized a two and
half day summer short course on Principles
of and Recent Advances in Laser Micro/Nano Manufacturing Processes.
This was held from June 1 to 4, 2010, in Evanston, Illinois with
more than 60 participants.
Speakers were leading researchers and practitioners from industry,
government and academia. Please find the details from the
short course web
