We present the generation of optical pulses with a spectral range of 500-2400 nm and energies up to 10 µJ at 1 kHz repetition rate by cascaded second-order nonlinear interaction of few-cycle pulses in beta-barium borate (BBO). Numerical simulations with a 1D+time split-step model are performed to explain the experimental findings. The large bandwidth and smooth spectral amplitude of the resulting pulses make them an ideal seed for ultra-broadband optical parametric chirped pulse amplification and an attractive source for spectroscopic applications.
我们展示了通过在β-硼酸钡（BBO）中对少周期脉冲进行级联二阶非线性相互作用，产生光谱范围为500 - 2400 nm、能量高达10 µJ且重复频率为1 kHz的光脉冲。采用一维加时间分步模型进行数值模拟以解释实验结果。所产生脉冲的大带宽和平滑光谱幅度使其成为超宽带光参量啁啾脉冲放大的理想种子源以及光谱应用的有吸引力的光源。
