AgGaSe2 OPO Pumped by a LiNbO3 OPO
Advanced Solid State Lasers, 1993An all solid state tunable I.R. laser source is described. A Q-switch Nd:YAG laser at 1.064 µm is used to pump two optical parametric oscillators (O.P.O.) in series. The first O.P.O. uses a LiNbO3 crystal and works in the vicinity of degeneracy. Its signal beam (adjusted at 1.82 µm) is used as a pump for the second O.P.O.

Phase Change Thermal Energy Storage Enabled by an In Situ Formed Porous TiO2.
Small, 2022Uneven and insufficient encapsulation caused by surface tension between supporting and phase change materials (PCMs) can be theoretically avoided if the encapsulation process co-occurs with the formation of supporting materials in the same environment ...

Microcavity Photonic Crystal OPO
Nonlinear Guided Waves and Their Applications, 2005We study the excitation of a defect mode in a quadratically nonlinear photonic crystal by a second harmonic wave. Both, a mean-field approach and finite-difference time-domain calculations predict spontaneous parametric down-conversion above a certain threshold.

Sistem Pengelolaan Pendidikan di MA Raudatul Muta’allimin Opo-Opo Krejengan Probolinggo Tahun 2021
BAHTSUNA: Jurnal Penelitian Pendidikan Islam, 2022Abstract The school as an educational management institution is the second institution after the family which consists of several elements, including the principal, teachers, employees, students and errand boys or school managers. So it is necessary to have an established management and organization so that educational activities run smoothly ...

SPIE Proceedings, 2009
The mid-infrared spectral region is of significant interest due to the atmospheric absorption lines present in this region. We report the development of a compact, highly efficient, high power intra-cavity pumped all-solid-state optical parametric oscillator (OPO) producing nanosecond pulses with an output tunable from 1.5 microns to 3.4 microns with

This dissertation describes OPOS, a C++ software library and framework for developing massively parallel continuous optimization software. We show that classical iterative optimization algorithms such as gradient projection and augmented Lagrangian methods can be parallelized to run efficiently on distributed memory machines using OPOS.In Chapter 1 we ...

Organ procurement organization (OPO), best practices
Clinical Transplantation, 2001There are currently 59 organ procurement organizations (OPOs) in the United States which serve their assigned geographic areas with variable productivity. Knowledge of organizational characteristics, programs and practices of more successful OPOs may be useful to increase the productivity of less successful OPOs.
