Femtosecond lasers offer unique characteristics in both the temporal and spectral terms, not observed in other continuous-wave or pulse lasers, permitting breakthroughs in precision dimensional metrology particularly. The temporal and spectral characteristics of femtosecond lasers were exploited in absolute distance measurement by means of pulse cross-correlation based interferometer and dual-comb interferometer which enable nanometer precision not only in laboratory environment but also in open-field. In this talk, absolute distance measurement technique will be described after brief introduction of femtosecond lasers and second half of the talk will be devoted to feasibility test of absolute optical testing exploiting distance measurement overcoming relative testing nature of conventional laser interferometer.

Thursday, April 25, 1 pm ET/10 am PT

Dae Wook Kim will discuss various new approaches for advancing the current computer controlled optical surfacing process for manufacturing highly aspheric or free-form optics, such as 8.4-meter diameter Giant Magellan Telescope off-axis primary segment at the U of A. He will also present actual data demonstrating the performance of the enhanced process to build next generation optical systems.

During the Spring 2012 semester LOFT partly sponsored the creation of 66 optics kits. 50 were donated to the Girl Scouts of Southern Arizona and 16 to CIAN (Center for Integrated Access Networks) from OSC. On November 12th 2012, a couple LOFT members gave training to the Scouts on how to use these kits and explain the optics behind the different experiments. 

Optimax, a principal partner with the College of Optical Sciences (OSC) Industrial Affiliates program, is offering a $10,000 Optimax Product Grant for Research.

Title: Benefits of molding fused silica with a focus on cost savings of raw material and CNC machine time

David’s career has focused on new process, product and business development in glass (most notably in fused silica and fused quartz glasses) and glass-ceramics primarily focused in advanced optical products in the Photonics areas. Areas of expertise include advanced lasers, optical instrumentation, semiconductors optical metrology, microlithography, aerospace optics, astronomy, optics used in military and scientific R&D.  Over the past 20 years, David has managed the development of over 30 new technology enabling products used by many tier-one manufacturers in these fields and has been responsible for development new business exceeding $100M’s business for Corning, Lucent & Heraeus.
