锁相单周期瞬态与频率分量之间的1和60太赫兹和峰值字段高达12 MV/cm的产生作为空闲波的参量放大器。为了在GaSe非线性晶体中实现宽带转换，我们匹配信号和闲频分量的群速度。在1.18 μ m的长波长泵浦下，群速度色散的影响被最小化。自由空间电光采样监测直接场分辨率的多太赫兹波形。(C)2010年美国光学学会
Phase-locked single-cycle transients with frequency components between 1 and 60 THz and peak fields of up to 12 MV/cm are generated as the idler wave of a parametric amplifier. To achieve broadband conversion in GaSe nonlinear crystals, we match the group velocities of signal and idler components. The influence of group-velocity dispersion is minimized by long-wavelength pumping at 1.18 mu m. Free-space electro-optic sampling monitors the multiterahertz waveforms with direct field resolution.
