Title: “Ultrafast Parametric Laser Sources in MIR and LWIR for Filamentation Research“

Abstract: Ultrashort-pulse lasers (USPLs) enable a wide range of applications in remote sensing, laser wakefield accelerations and directed energy. The underlying physical effects for many of those applications scale favorably with the laser wavelength and can benefit from using optical sources operating in the mid-infrared (MIR) and long-wave infrared (LWIR) spectral ranges. Yet to-date, most of the investigations in strong-field laser-matter interactions utilized high-energy USPLs operating in the relatively narrow wavelength range in the near-infrared. Developments of new nonlinear optical materials and optical parametric chirped-pulse amplification (OPCPA) technology enable efficient conversion of widely available near-infrared laser sources to longer wavelengths favored by applications. We will discuss two projects targeting the construction of energetic long-wavelength USPL OPCPAs: a TW-class LWIR source at the University of Arizona and a GW-class MIR source at the AFRL Kirtland.

Bio: Jacob Barker is a 4th year PhD student under Dr. Pavel Polynkin. Research interests include new USPL sources, filamentation, turbulence effects, and adaptive optics.

Title: “Low-Quantum-Defect Single Frequency Fiber Laser“

Abstract: Low quantum defect lasers generally suffer from less thermal issues due to the less heat generation in the laser operation. In this talk, we will present a single-frequency distributed-Bragg-reflector fiber laser emitting at 980 nm with quantum defect of less than 0.6%. A maximum output power of 275 mW with a slope efficiency of 50% with respect to the launched pump power was obtained with a 1.5-cm high ytterbium-doped phosphate fiber. This research demonstrated the possibility to achieve single-frequency laser source with ultra-low thermal noises.

Title: “Development of Glass Molding Technology for the MODE Lens Telescope“

Abstract: Recent developments in spaceflight technology have drastically decreased the cost of space launches and projections show that this trend will continue. For space telescopes to properly take advantage of this decrease in cost, they must be designed to be very lightweight and fabricated in a scalable method. The design of the MODE lens telescope offers a design with a very lightweight objective lens which is designed as an achromat. By fabricating MODE lens objective using a molding process, we will be able to make a large number of lightweight telescopes which can simulate the effect of single, extremely large telescope.

Title: “Pinwheels: a Curved Aperture Segmentation Topology for Improved Astrophysical Science on Future Observatories“

Abstract: Pinwheel segmentation is a novel curved-edge segmentation topology capable of emulating a monolithic circular aperture by generating a “quasi-Airy” point spread function. A brief overview of the theory and construction of pinwheel apertures is given. In addition, pinwheel segmentation for coronagraphy and crowded field imaging is demonstrated in simulation and compared with a circular monolithic aperture and a hexagonally segmented aperture.

Title: “Lens-Free Time-Gated Fluorescence Microscopy“

Abstract: Our research aims to develop a lens-free time-gated fluorescent imaging technique for high-resolution imaging of labeled cells. Unlike lens-based microscopes, lens-free techniques generally have large field of views limited only by the size of their sensor arrays. Unfortunately, due to the incoherence of fluorescent emitters and the necessary barrier filter placed between the sample and sensor, lens-free methods struggle to reach micron size resolution. Our design overcomes this issue by removing the chromatic filter and implementing a time-gated exposure technique, decreasing the sample to sensor distance. We demonstrate that this method reaches sub-10 µm resolution when placed directly upon the sensor. Additionally, we propose a nanoparticle-based shift variant scattering mask to help repropagate diffraction limited information to the detector for use in a computational reconstruction technique.

Bio: Kenneth Lang is a first year PhD student at the Wyant College of Optical Science. He has research interests in nano-photonics, metamaterials, and computational imaging. Kenneth is currently working on developing lens-free imaging systems and utilizing nanoparticle structures for computational image reconstruction methods.

Title: “Particle Population Analysis for Automated Assembly Using Optical Tweezers“

Abstract: The optical positioning and linking (OPAL) platform has enabled the assembly of complex 3D microstructures and augmentation of existing devices using optical tweezers and a biochemical linking mechanism. While the assembly process is currently semi-automated, a fully automated system would increase efficiency but requires knowing how many particles are trapped at any given time. The backscattered signal from trapped particles is characteristic of the particle size, material, and number of particles in the trap and can be analyzed using a quadrant photodiode (QPD). By applying principal component analysis and a support vector machine to processed data from the QPD, we show it is possible to classify the number of trapped particles for a given particle size and material. Incorporating this data collection and processing into the current assembly procedure will allow for particle population determination that can be used for automated assembly and increased throughput.

Bio: Natalie is a second year PhD student working in the Soft Nano-Photonics Systems Laboratory under Dr. Euan McLeod. The focus of her research is the design and assembly of microstructures using optical tweezers.

Title: “Ptychographic Array Cameras for Synthetic Aperture Lidar“

Abstract: Under partially coherent illumination the structure of images changes with camera position. This effect can be used to coherently combine data from camera arrays for super-resolution and 3D imaging. This talk describes the theory of actively illuminated array cameras and presents recent experimental progress in implementing such systems.

Title: “Scatter Ptychography“

Abstract: Diffraction limits the minimum resolvable feature on remotely observed targets, and the resolution will be further reduced by scatter or turbulence. Here we demonstrate the analysis of scattered coherent illumination that can use to achieve a resolution proportional to the range between the scatter and the target and the diameter of the observed scatter. We present laboratory results demonstrating >30X and field experiment >10X improvement.
