Abstract

A polarizer design that combines many of the desirable qualities of crystal polarizers with many of the desirable qualities of beamsplitting cube polarizers fabricated with high power handling glasses and thin film coating manufacture processes. Namely, the present design achieves a high extinction ratio (>100,000:1 Tp/Ts) over a broad optical bandwidth (Δλ/λ>0.1), with high power and pulse energy handling with the additional benefits of all four input/output ports being high optical quality surfaces (different from many crystal polarizers), high transmission (Tp>98%), and low dispersion in the thin film and low bulk material dispersion (group velocity dispersions of 72, 21, and −22 fs2/mm at 500, 1000, and 1500 nm respectively).

Abstract

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. The present method overcomes the shortcoming that existing methods of etching structures directly on a substrate would require a different etching recipe for each substrate made of a different material.

Abstract

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.

Abstract

The conical ball cone bearing is a high load and reduced pressure kinematic or fixed thrust bearing that allows for a greater load carrying 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.

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.

Abstract

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).

Abstract

A tunable source includes a short-cavity laser optimized for performance and reliability in SSOCT imaging systems, spectroscopic detection systems, and other types of detection and sensing systems. The short cavity laser has a large free spectral range cavity, fast tuning response and single transverse, longitudinal and polarization mode operation, and includes embodiments for fast and wide tuning, and optimized spectral shaping. Disclosed are both electrical and optical pumping in a MEMS-VCSEL geometry with mirror and gain regions optimized for wide tuning, high output power, and a variety of preferred wavelength ranges; and a semiconductor optical amplifier, combined with the short-cavity laser to produce high-power, spectrally shaped operation. Several preferred imaging and detection systems make use of this tunable source for optimized operation are also disclosed.
