We study the properties of dissipative solitons supported by a chirped lattice in a focusing Kerr medium with nonlinear loss and a transversal linear gain landscape consisting of single or three amplifying channels. The existence and stability of two types of dissipative solitons, including fundamental and three-peaked twisted solitons, have been explored. Stable fundamental solitons can only be found in a single-channel gain chirped lattice, and stable three-peaked twisted solitons can only be obtained in a three-channel gain chirped lattice. The instability of two types of dissipative solitons can be suppressed at a high chirp rate. Also, robust fundamental and three-peaked twisted nonlinear states can be obtained by excitation of Gaussian beams of arbitrary width in corresponding characteristic structures.

横向单通道或三通道放大chi格支持的耗散孤子。

我们研究了在聚焦Kerr介质中a的晶格支持的耗散孤子的特性，该介质具有非线性损耗和由单个或三个放大通道组成的横向线性增益景观。已经探究了两种耗散孤子的存在和稳定性，包括基本和三峰扭曲孤子。稳定的基本孤子只能在单通道增益chi晶格中找到，而稳定的三峰扭曲孤子只能在三通道增益chi晶格中获得。可以以高chi速率抑制两种耗散孤子的不稳定性。而且，通过在相应的特征结构中激励任意宽度的高斯光束，可以获得鲁棒的基波和三峰扭曲非线性状态。
