This Engineering Research Equipment Grant will support Watts of modelocked power at 1.053 um. This laser, which generates 50 picosecond pulses, will be used to pump a near IR femtosecond dye laser, and also seed a Nd:YLF regenerative amplifier. The proposed Nd:YLF laser will replace our failing Nd:YAG laser and provide us with the needed reliability and stability necessary to carry out planned fundamental and device studies on GaAs based samples. It will also allow us to extend our femtosecond system operating wavelength from 870nm to 1.3 um and enable us to expand our time- resolved studies of optical nonlinearities to narrow gap InGaAs semiconductor materials.

这项工程研究设备赠款将支持1.053微米的模型锁定功率瓦特。该激光器产生50皮秒脉冲，将用于泵浦近红外飞秒染料激光器，还将用于种子再生放大器。拟议中的Nd：YLF激光器将取代我们失败的Nd：YAG激光器，并为我们提供必要的可靠性和稳定性，以便对基于GaAs的样品进行计划中的基础和器件研究。它还将使我们能够将我们的飞秒系统工作波长从870 nm扩展到1.3微米，并使我们能够将我们对光学非线性的时间分辨研究扩展到窄禁带InGaAs半导体材料。
