Spontaneous creation of solitons in quadratic media by the downconversion (i.e., parametric instability against the generation of fundamental-frequency excitations) from the truncated Airy-wave (AW) mode in the second-harmonic component is studied. Parameter regions are identified for the generation of one, two, and three solitons, with additional small-amplitude "jets." Shares of the total power carried by individual solitons are found. Also considered are soliton patterns generated by the downconversion from a pair of AWs bending in opposite directions.
研究了二次谐波分量中截断艾里波（AW）模式通过下转换（即针对基频激发产生的参量不稳定性）在二次介质中自发产生孤子的现象。确定了产生一个、两个和三个孤子以及额外小振幅“射流”的参数区域。发现了各个孤子所携带的总功率份额。还考虑了由一对向相反方向弯曲的AWs下转换产生的孤子模式。
