SUMMARY of RESEARCH EXPERIENCE and EMPLOYMENT ACTIVITIES LCLS Laser Group: I have been working in the LCLS laser group to assist Users at the LCLS x-ray hutches, as well as to support the SLAC Laser Group and LCLS Instrument Scientists on in- house laser system research and development. In this role, I have worked with Users from diverse scientific backgrounds, facilitating experimental design/execution and data collection, as well as supporting data analysis and the dissemination of scientific findings. I enable the use of, and the service for, light sources including standard 800nm optical lasers, optical parametric amplifiers, and the various difference, sum, and doubling schemes for generating light from the UV to the mid – IR, as required by Users. I have also worked extensively with Dr. Ryan Coffee and others to develop new measurement and characterization

methodologies at the LCLS. These include the use of molecular alignment to observe quasi-bound dication states of molecular nitrogen, and the development of optical/x-ray cross correlators to help characterize the LCLS. High Intensity Gas Phase Experiments: I worked on my graduate studies at Stanford starting in June 2006. I am an atomic physicist and my primary research interests and experience have been studies of the interaction of intense lasers with gas phase atoms and molecules. I initially helped complete the commissioning of the attosecond high harmonic lab, which was the first lab constructed for the PULSE Institute for Ultrafast Science. There, I developed various experimental capabilities, including ultrafast laser sources and vacuum systems, and assisted in the first experiments to characterize the carrier envelope phase stability of a Ti:Sapphire laser. I then transitioned to a different lab at SLAC where I am currently completing my thesis research. Here we use strong laser fields to manipulate the excited states of diatomic molecules and control vibrational and rotational behavior. To help accomplish this work, I designed and constructed a novel dual color OPA to manipulate and observe molecular dynamics. This OPA is unique in that the two tunable colors it produces are seeded from a common white light source, which gives the source unique phase stability required for the manipulation and control. In addition to the laser lab based work, I participated in the initial commissioning of the LCLS, being directly involved in the first experimental runs completed at the LCLS. Since then, I continue to be involved with various LCLS experiments on a frequent basis, and achieved an LCLS run through a successful User proposal, as co-PI, for an experimental run completed in April 2012 that studied coulomb explosion imaging of vibrational wavepackets. I have also either written or been a co-author on many LCLS papers, and have given numerous presentations on work done at the LCLS. Commissioning an attosecond dynamics research lab: At Stanford, but prior to beginning graduate studies, I was hired by Dr. Bucksbaum to help build and commission the first ultrafast laser lab at the PULSE Institute, to enable the use of harmonics from a Ti:Sapphire amplifier to study fundamental atomic and molecular dynamics. Basically starting with an empty room, I was charged to lead the design and build a suite experimental of experimental capabilities, including vacuum chambers, light sources, and detection equipment. Also, this was the first SLAC directed laser research lab located entirely on the Stanford campus, which required navigating the interface between Stanford and SLAC purchasing, safety, property, and financial departments being required to make the new lab operational. The lab now serves as a standard model for research labs at SLAC, featuring the use of water cooled computer server racks to house laser components, now used extensively throughout all PULSE labs. New high intensity ultrafast laser sources and Plasmonics for ultrasensitive molecular detection: At Los Alamos, I completed a design review of an all reflective pulse stretcher compressor (numerically modeled) and a high power, multipass, Ti:Sapphire amplifier system employing cryogenic cooling (controlling thermal effects) to enable new high-field laser plasma experiments. I also continued to explore the use of plasmonic structures for ultrasensitive detection (described below) and for nanoplasmonic devices. Plasmonics for ultrasensitive molecular detection: At Los Alamos, I explored new approaches for sample preparation, as well as techniques to introduce the assay sample onto plasmonic structures. I also redesigned and rebuilt the experimental optical configuration (a helium neon laser / prism beam deviation / LabVIEW interface). In this approach, light incident upon a metal nanoparticle (Au) excites a collective electron oscillation with a restoring force provided by the induced surface polarization resulting in distinct plasmon resonance absorption. Associated with the plasmon resonance is an enhanced local electric field (e. g. the local intensity can be ~100X, or more, than the incident intensity). This enhancement depends on the wavelength and the dielectric function of the metal and the surrounding dielectric medium. In the case of the thin metal film is a non-radiative evanescent mode consisting of a charge density modulation with amplitude that exponentially decays over a distance of ~100 nm normal to the surface. The decaying evanescent field is extremely sensitive to the local dielectric medium and this allows for SPPs to be exploited as a tool for ultrasensitive molecular detection and bioassays.

New high intensity ultrafast laser source: At Los Alamos, I undertook a project to upgrade one of the LUMOS group’s ultrafast laser amplifier capabilities by constructing a new multipass chirped pulse Ti:sapphire laser amplifier and an all reflective pulse stretcher/compressor with high mechanical stability and optimal optical configuration. The stretcher/compressor was numerically modeled using an ABCD ray matrix approach. All mechanical designs were optimized, I specified and ordered all components, and fabricated many of the mechanical components. I also built a pulse characterization apparatus (single-shot autocorrelator). New high power, high repetition rate, narrow band laser oscillator/amplifier source: At the University of Michigan as a REU participant, I designed and constructed a high energy, high repetition rate, high spatial beam quality, and narrow bandwidth dye laser system. This work required the review of a number of possible designs for the oscillator with consideration of the dye flow characteristics (due to thermal loading) and dye cell/dye jet strategies. My final design used a standing wave oscillator with intracavity etalons and an amplifier stage utilizing a high flow dye cell to control the thermal loading of the gain medium. This laser met the required specifications where it ran at 646 nm and had a frequency bandwidth ~0.3 GHz. The final output pulse energy, after amplification and a second harmonic conversion crystal, was ~10 µJ at 323 nm, as was required for the experiment. This laser was used to excite lithium atoms to a launch state facilitating the creation of Rydberg atoms. Refurbish / Repair of commercial Nd:YAG laser: At the University of Michigan as a REU participant, I refurbished a Quanta-Ray DCR-2A Nd:YAG laser that was inoperable. I refurbished mechanical portions of the power supply and laser head, rebuilt some control and driver circuitry, and cleaned, refurbished, and realigned the optical cavity. The laser was made operable by the end of this internship. I later worked with students in Professor Chris Monroe’s group during the following summer (2002) to optimize a harmonic generator to produce the fourth-harmonic radiation with this laser. Measures of photon localization: At the University of Michigan as a REU participant, I developed and constructed an interferometric based coherent backscattering apparatus used to investigate the localization of light in very fine rare earth rare earth doped nano-crystalline aluminum oxide powers and rare earth crystals. I also performed spectrophotometric analyses of diamond thin film materials used in the development of color center lasers. Spectral Studies of Laser-Induced Sonoluminescence: At IBM Research, I proposed and performed an experimental investigation of laser cavitated sonoluminescence, under the mentorship of Dr. Richard Haight. The result of this study was the first reported spectrally resolved result of this phenomenon (presented at an OSA annual meeting).
