论文摘要
我们证明了焦耳级别的最高效率（$ \ sim $ 80％）第二次谐波生成（SHG），27 femtsecond，高对比度脉冲中的高对比度脉冲（LBO）晶体中。相比之下，二氢钾（KDP）的最大效率为26％。因此，LBO提供了高强度（$> $ 10 $^{19} $ w/cm $^{2} $），超高的对比度飞秒脉冲，这些脉冲具有巨大的潜力，这对于高能量密度科学尤其是纳米结构的目标以及技术应用。
We demonstrate the highest efficiency ($\sim$80%) second harmonic generation (SHG) of Joule level, 27 femtosecond, high contrast pulses in a type-I lithium triborate (LBO) crystal. In comparison, potassium dihydrogen phosphate (KDP) gives a maximum efficiency of 26%. LBO thus offers high intensity ($>$10$^{19}$ W/cm$^{2}$), ultra-high contrast femtosecond pulses, which have great potential for high energy density science particularly with nanostructured targets as well as technological applications.
