High-Energy Cavity-Dumped Ti:Sapphire Oscillator and Applications

这项提案寻求资金，以建立一个使用电光调制器的高能腔倾倒激光系统。这项工作是PI根据国家科学基金会职业奖(PHY-9502935)取得的先前成就的延伸。PI已经展示了一种EO腔倾倒激光系统，它在20fs内以1 kHz的重复频率产生了200nJ的能量，这是最先进的声光(AO)腔倾倒激光系统的两倍能量。与声光晶体相比，电光空腔倾倒的优点是由于声光晶体的非线性过程，使声光晶体在高功率下不稳定。PI预测，EO腔倾倒激光系统的理论最大能量仍然是已证明的50倍，重复频率高达10 MHz是可能的。这项提议是为了改进最初的设计，并实现比他所展示的更高的激光系统能量。

This proposal seeks funding to build a high energy, cavity dumped laser system using EO modulators. The work is an extension of previous accomplishment by the PI under a NSF CAREER award (PHY-9502935). The PI has demonstrated an EO cavity-dumped laser system that has produced 200nJ of energy in 20 fsec at 1 KHz repetition rate, which is twice the energy of the state-of-the-art acuosto-optic (AO) cavity-dumped laser system. The advantage of the EO cavity-dumping over that of AO is that the latter suffers instability at high powers due to the nonlinear process of the AO crystal. The PI predicted that the theoretical maximum energy of an EO cavity dumped laser system is still 50 times what has been demonstrated, and that a repetition rate as high as 10 MHz is possible. This proposal is to improve the original design and to achieve even higher energy of the laser system than he has demonstrated.
