Power Scaling of CW Crystalline OPOs and Raman Lasers

Photonics, 2021
Optical parametric oscillators (OPOs) and Raman lasers are two nonlinear-based laser technologies that extend the spectral range of conventional inversion lasers.

OPOS [PDF]

Proceedings of the 5th Nordic conference on Human-computer interaction: building bridges, 2008
The concept of Head-Up Games [18] advocates that pervasive games of the future should be designed to evoke play patterns akin to those of traditional outdoor games. This tenet, while appealing, is ill defined without a clear description of these behaviors.

Beam quality and efficiency of ns-pulsed high-power mid-IR ZGP OPOs compared in linear and non-planar ring resonators.

Optics Express, 2021
We compare the performance of ns-pulsed mid-infrared optical parametric oscillators (OPOs) based on ZGP crystals in a simple linear cavity and two non-planar image-rotating resonators. Our 2 μm pump source is a 68 W 10 kHz diffraction limited Ho:LLF MOPA

Procurement characteristics of high‐ and low‐performing OPOs as seen in OPTN/SRTR data

American Journal of Transplantation, 2021
To meet new Centers for Medicare and Medicaid Services (CMS) metrics, organ procurement organizations (OPOs) will benefit from understanding performance across decedent and hospital types.

Ultralow-threshold thin-film lithium niobate optical parametric oscillator [PDF]

Optica, 2021
Materials with strong χ (2) optical nonlinearity, especially lithium niobate, play a critical role in building optical parametric oscillators (OPOs). However, chip-scale integration of low-loss χ (2) materials remains challenging and limits the threshold

A Coherent Ising Machine Based On Degenerate Optical Parametric Oscillators [PDF]

, 2013
A degenerate optical parametric oscillator network is proposed to solve the NP-hard problem of finding a ground state of the Ising model. The underlying operating mechanism originates from the bistable output phase of each oscillator and the inherent ...

Regional Variation in Transplant Utilization and Agonal Times among Donation after Circulatory Death Lung Donors in the United States. [PDF]

Clin Transplant
ABSTRACT Introduction Utilization of donation after circulatory death (DCD) donors in lung transplant in the United States lags when compared to other countries. We sought to evaluate geographical variation in the percentage of donation after circulatory death donors, conversion to lung transplant, agonal times, and consent for donation.

Opium trade and use during the Late Bronze Age: Organic residue analysis of ceramic vessels from the burials of Tel Yehud, Israel

Archaeometry, EarlyView., 2022
Abstract Organic residue analysis was conducted on various vessels from burials at Tel Yehud, Israel. The analyses led to new reliable evidence for the presence of opioid alkaloids and their decomposition products. This research revitalizes a decades‐old discussion on the presence and function of the opium trade across a cultural region of utmost ...
