The threshold of lithium tantalite under single-shot is found to be 1.84J /cm 2 and the avalanche rate was determined to be 1.01 cm 2 /J by calculation. We found that avalanche dominates the ablation process, while photoionization serves as a free electron provider.

在800nm飞秒激光脉冲作用下，钽酸锂晶体单脉冲烧蚀阈值为1.84 J /cm 2；在此基础上，我们通过建立钽酸锂晶体中导带电子密度演化微分方程，并数值求解，得到了钽酸锂的碰撞电离速率系数为1.01 cm 2 /J ，并得出在钽酸锂表面烧蚀中，光致电离提供种子电子，雪崩电离起主导作用的结论。
