摘要： An optical probe for measuring physical and chemical characteristics of a transparent fluid medium during flow comprises two fingers parallel to one another and to the flow. Each finger consists of a solid bar of transparent material, in which a light beam propagates and is reflected on an end face of the bar, said face being situated upstream in the flow. Such an optical probe may be reduced in size, and provides results which are less sensitive to disturbances of the flow that are caused by the probe itself.

摘要： The invention applies to doubly resonant optical parametric oscillators comprising a non-linear crystal (4) through which pass a pump laser beam (fp), a signal beam (fs), and a complementary beam (fc), and a device (5) that totally or partially reflects said beams emanating from the crystal such that, after reflection, they generate between them a relative phase-shifting value ΔΦar for a given functioning mode independent of the signal frequency or complementary frequency, and is characterized in that the reflecting device (5) is a metallic minor, or a combination of two scattering mirrors and a multilayer dielectric mirror placed downstream.
