In a method of producing an anti-reflective surface, instead of etching subwavelength structures directly onto the substrate, a thin film layer of topcoat is deposited onto the surface of the substrate, and the anti-reflective surface is created by etching the structures into the topcoat. Because the thin film can be applied to substrates made of a large number of different materials, only common etching recipes need to be developed for a few thin film materials.

A system and method of producing energetic laser pulses suitable for multi-photon microscopy, in which laser pulses from an ultrafast pump source operating at greater than 40 MHz repetition rate are directed onto an optical cavity, where the pulses build-up to a higher energy inside of that cavity over the period of many pulses. After the intra-cavity pulses achieve sufficient energy, an active element inside of the cavity switches out the enhanced light pulse with a reduced a repetition rate relative to the pump source. The increased pulse energy and reduced repetition rate will enable the pump source, originally designed for two-photon microscopy, to perform new imaging modalities, such as deep, in-vivo, three-photon microscopy.

ABSTRACTThe conical ball cone bearing is a high load and reduced pressure kinematic or fixed thrust bearing that allows for a greater load canying capacity with a reduced contact pressure to be obtained in a smaller package. This bearing maximizes the contact radius over the needed angular translation to reduce the contact pressure. This has two advantages in a kinematic system. First, the reduced contact pressure increases the maximum load the bearing can hold prior to surface failure. Second, the reduced contact pressure reduces the friction on the kinematic contacts, allowing the kinematic system to move more freely and operate with a smoother movement and improved stability.Date Recue/Date Received 2022-09-22

Abstract
This disclosure relates to combined frequency and angle compounding for speckle reduction in ultrasound imaging. Such combined frequency and angle compounding can result in a multiplicative speckle reduction compared to using either frequency compounding or angle compounding alone. Compounding methods of this disclosure can make use of the full aperture of the ultrasound probe when acquiring individual images, hence there can be no compromise in resolution. In disclosed embodiments, ultrasound images can be obtained while an ultrasound probe is moving and the relative position and orientation of the ultrasound images can be determined from a measurement of the position and orientation of the ultrasound probe. Certain embodiments can correct for the movement and distortion of an object being imaged during the image acquisition.

Higher-order dispersion compensating pulse shaper via amplitude spectral filtering and nonlinear phase accumulation
A method of pulse shaping using spectral filtering, positive chirp, and self-phase modulation to control the accumulated higher-order phase terms of the spectral phase. This pulse shaping method has particular advantage in fiber chirped pulse amplification (FCPA) systems, where there are two effects: (1) an offsetting of the fourth order phase via nonlinear phase accumulation, allowing for a higher Strehl ratio (i.e., a cleaner pulse), higher peak power pulse and (2) enabling power scaling to higher pulse energies without the increased nonlinear phase accumulation leading to pulse breakup. This technique can be used both in a passive system with no amplification to clean up an existing pulse, and in an amplifier system to enable higher performance operation (shorter pulses, cleaner pulses, higher energy pulses).

Use of electronically controlled polarization elements for the initiation and optimization of laser mode-locking
Apparatus for modelocking a fiber laser cavity includes two variable retarder assemblies and a polarizing element. The variable retarder assemblies each have two electronically addressable elements and one fixed element. The first variable retarder assembly prepares a polarization state suitable for NPE modelocking to be launched into the fiber, and the second variable retarder assembly controls the polarization state after exiting the fiber, before being incident on the polarizing element. A control system controls the electronically addressable phase retarders in order to create and modify conditions for modelocking the fiber laser.

Technique for optimizing coupling to optical fibers
A method of optimizing the coupling to an optical fiber, including: generating a femtosecond laser pulse; directing a focus of the laser pulse to a longitudinal depth in the region beneath the endface of the optical fiber to generate microvoids; adjusting the intensity of the laser pulse at different depths, such that a refractive index profile is created in the region beneath the endface of the optical fiber.

An optical material including: a silica host; and a Praseodymium dopant; wherein the Praseodymium atoms are configured to form nanoclusters in the silica host. In addition, the optical material may include an Ytterbium co-dopant. The nanoclusters include Ge, Te, Ta, Lu and/or F, Cl to minimize multi-phonon quenching. Moreover, the nanoclusters may be encapsulated in a low phonon energy shell to minimize energy transfer to the host matrix.
