Conversion of truncated Airy waves (AWs) carried by the second-harmonic (SH) component into axisymmetric χ solitons is considered in a 2D system with quadratic nonlinearity. The spontaneous conversion is driven by the parametric instability of the SH wave. The input in the form of the AW vortex is also considered. As a result, one, two, or three stable solitons emerge in a well-defined form, unlike the recently studied 1D setting, where the picture is obscured by radiation jets. Shares of the total power captured by the emerging solitons and conversion efficiency are found as functions of parameters of the AW input.
在具有二次非线性的二维系统中，研究了由二次谐波（SH）分量携带的截断艾里波（AWs）向轴对称χ孤子的转换。自发转换由SH波的参量不稳定性驱动。还考虑了AW涡旋形式的输入。结果，与最近研究的一维情况不同，一维情况中图像被辐射喷流所掩盖，在这里会以明确的形式出现一个、两个或三个稳定孤子。发现出现的孤子捕获的总功率份额和转换效率是AW输入参数的函数。
