An ultrafast laser hardware upgrade is requested, in the form of a cavity length stabilizer for an existing mode-locked Ti:sapphire oscillator. The upgrade will enable powerful frequency-domain excitation / time-domain detection stroboscopic microscopy measurements to elucidate dynamics in nanostructures. These will be accomplished by synchronizing the laser pulse repetition frequency to an external Rubidium clock (where the latter also supplies the time base for a microwave synthesizer).

超快激光器硬件升级的要求，在现有的锁模钛：蓝宝石振荡器的腔长稳定器的形式。 升级将使强大的频域激发/时域检测频闪显微镜测量，以阐明纳米结构的动态。 这些将通过将激光脉冲重复频率与外部铷钟同步来实现（后者还为微波合成器提供时基）。
