Acquisition of Ti/Sapphire Amplifier for Upgrading Powerful Subpicosecond Laser Facility

该提案要求提供资金，用于升级现有的普林斯顿亚皮秒激光设备，将现有的KRF放大器替换为600MJ、10赫兹重复率、多程钛/蓝宝石放大器。申请的资金用于从一家商业公司直接购买该系统。升级系统的第一个目标是进一步探索在光谱的“水窗口”区域开发一种对生物应用具有潜在价值的紧凑型软x射线激光器的想法。同时，该设施将为来自不同系的教职员工和研究生提供多学科项目的资源，包括亚皮秒脉冲的拉曼放大、固体材料表面改性的研究，以及半导体材料薄层性质变化的研究。

This proposal requests funds to upgrade the existing Princeton Subpicosecond Laser Facility by replacing the current KrF amplifiers with a 600 mJ, 10 Hz repetition rate, multipass Ti/Sapphire amplifier. The funds requested are for direct purchase of the system from a commercial company. The first objective of the upgraded system is to further exploit ideas for the development of a compact soft x-ray laser in the "water window" region of the spectrum that is potentially so valuable for biological applications. At the same time, the facility would serve as a resource for faculty members and graduate students from different departments in multi-disciplinary projects, including Raman amplification of subpicosecond pulses, study of surface modification of solid materials, and the study of property changes in thin layers of semiconductor materials.
