We demonstrate phase-matched difference frequency generation in the emerging nonlinear crystal LaGaTaO. Tunable wavelengths between 1.4 and 4.7 μm are generated by using femtosecond sources. We also report on the measurements of the optical damage threshold in the femtosecond regime and on the nonlinear refractive index n.

December 2024
Haematology Research, Murdoch Children's Research Institute, Melbourne, VIC, Australia.
Objectives: To determine if a priori standardization of outcome hemostatic definitions alone was adequate to enable useful comparison between two cohorts of pediatric extracorporeal membrane oxygenation (ECMO) patients, managed according to local practice and protocol.
Design: Comparison of two separate prospective cohort studies performed at different centers with standardized outcome definitions agreed upon a priori.
Setting: General and cardiac PICUs at the Royal Children's Hospital (RCH) in Melbourne, Australia, and the Sophia Children's Hospital (SCH) in Rotterdam, The Netherlands.
