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

该提案寻求资金，以建立一个高能量，腔倒空激光系统使用EO调制器。 这项工作是由PI根据NSF职业奖（PHY-9502935）以前的成就的延伸。 PI已经展示了一种EO腔倒空激光系统，该系统在1 KHz重复率下在20 fsec内产生200 nJ的能量，这是最先进的声光（AO）腔倒空激光系统能量的两倍。 EO腔倒空的优点是，由于AO晶体的非线性过程，后者在高功率下遭受不稳定性。 PI预测，EO腔倒空激光系统的理论最大能量仍然是已经证明的50倍，并且重复率高达10 MHz是可能的。 这个建议是为了改进原来的设计，并实现比他所证明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.
