Transverse patterns of mini-cavity optical parametric oscillator with seed injection

Abstract

We show experimentally, and interpret theoretically the conical and multiconical emission of optical parametric oscillators with seed injection in monolithic mini-cavities. We show the tunability of the conical emission angle, the switching between different resonant cones, and simultaneous emission on different cones, depending on the pump angle as well as on the length of the resonator.
