采用一阶螺旋拉盖尔-高斯模式(也称为圆环模式)来提高充气多程池中非线性光谱展宽的能量通量。在这封信中提出的方法,使第一次尽我们所知,能量超过100 mJ的脉冲的非线性光谱展宽,并适用于超过500 W的平均功率,同时保存一个优秀的空间-光谱均匀性为98%和高斯样的焦点轮廓。此外,从1.3 ps到37 fs的压缩性被证明。
The first-order helical Laguerre-Gaussian mode (also called donut mode) is used to improve the energy throughput of nonlinear spectral broadening in gas-filled multipass cells. The method proposed in this Letter enables, for the first time to the best of our knowledge, the nonlinear spectral broadening of pulses with energies beyond 100 mJ and is suitable for an average power of more than 500 W while conserving an excellent spatio-spectral homogeneity of ∼98% and a Gaussian-like focus profile. Additionally compressibility from 1.3 ps to 37 fs is demonstrated.
