We investigate the dependence of Cherenkov radiation (CR) on pump pulse parameters and its evolution along the propagation distance. Using a Ti:sapphire laser emitting 10 fs pulses as the pump source, we demonstrate highly efficient (>40%), broadband (>50 nm) CR in the visible-wavelength range with a threshold energy less than 100 pJ and a tuning range over 100 nm.
我们研究了切伦科夫辐射（CR）对泵浦脉冲参数的依赖性及其在传播距离上的演化。使用发射 10fs 脉冲的钛宝石激光器作为泵浦源，我们在可见波长范围内实现了高效率（>40%）、宽带（>50nm）的 CR，其阈值能量小于 100pJ，调谐范围超过 100nm。
