  • The 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.

  • The Center Industrial Advisory Board was held on Nov. 11 at Purdue University.  For details, please see

  • The successful new results of several projects carried out at the Center were presented at two upcoming conferences. Materials Sciences and 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.

  • Using the 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.

  • A recent 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.

  • Over the 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.

  • A second powder feeder has been acquired and installed on the Optomec LENS750 system.  The system now provides the capabilities of building gradient structures.

  • A new 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.

  • Our work on the ultrafast laser-based scribing of this film solar cells has been featured by a number of news media.  Please see the Media Coverage page to see the link.  

  • 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.

  • One of the Professor Shin's group's paper is among the most cited papers published in International Journal of Machine Tools and Manufacture from 2006 to 2010.  "Laser-assisted machining of Inconel 718 with an economic analysis" Volume 46, Issue 14, 2006, pp. 1879-1891 Anderson, M., Patwa, R., Shin, Y.C.

  • One of the Professor Shin's group's paper was shown to be among the hottest 25 papers from 2009 to 2010 in International Journal of Machine Tools and Manufacture.  "Machinability improvement of titanium alloy (Ti6Al4V) via LAM and hybrid machining", International Journal of Machine Tools and Manufacture, Volume 50, Issue 2, February 2010, Pages 174-182 Dandekar, C.R.; Shin, Y.C.; Barnes, J. 

  • 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 site.

  • The latest news media articles on our research in the laser-based fabrication of biomedical implants and stents have appeared in many different magazines and web news portal sites.  To see the articles, visit Press Release page.
