QEG’s scope of research is investigation of fundamental optical and quantum phenomena with a focus on developing advanced materials and technology for nanophotonic, biomedical, magnetooptic, and microfluidic devices. 

The Ultrashort Pulse (USP) Laser Spectroscopy and Nanomachining Laboratory

The Ultrashort Pulse (USP) Laser Spectroscopy and Nanomachining Laboratory was founded in the spring of 2014 with a $500,000 seed grant from the Army Research Office (ARO).  When completed, the laboratory will provide a source of ultrahigh intensity, sub 100 femtosecond laser pulses, covering the ultraviolet through the infrared spectrum (290-2,600 nm).  The goals of the facility are to 1) address fundamental questions that may provide new insights in USP laser-matter interactions and 2) develop systems and techniques for precision USP laser fabrication of Micro and Nanoelectromechanical devices. The laboratory facilities include:

  • Spectra physics Mai Tai fs oscillator
  • Spectra Physics SOLSTICE 3.5 W regenerative amplifier 1-10 kHz
  • Spectra Physics TOPAS Prime OPO 290-1160 nm
  • Spectra Physics TOPAS Prime OPO 1160-2600 nm
  • Newport Ultrashort Pulse Laser Direct-Writing Micro-nanomachining Workstation

Crystal Physics Laboratory

The discovery of new materials with exotic properties is essential for development of next generation technologies. In order to create fundamental physics based models of their properties precise measurements are needed that typically require single crystals.  The goal of the laboratory is to develop systems and techniques for fabrication of single crystals, from the nanoscale through bulk, with accurate control of their crystal chemistry such as point defects, structural dislocations, impurities, and dopant levels.  CPL is equipped with a state-of-the-art Crystal Systems Inc., Model FZ-T-2000-X-VII-VPO-PC optical float zone crystal growth system and associated equipment. Of particular interest are:

  • Multiferroic oxide and oxyfluoride perovskites,
  • Semiconducting topological insulators, and 
  • Bulk-nanoparticle composites.
