Abstract

A complete electronic system that is suitable for use in megahertz frequency domain time-resolved fluorescence instruments based on mode-locked lasers is described. The circuit produces a 10 MHz signal, phase locked to the mode-locked laser pulse frequency, which is required by many commercial frequency synthesizers as the external reference signal. This device is particularly useful in conjunction with ultrafast gated intensified charge coupled device cameras capable of being frequency modulated for time-resolved fluorescence imaging.

摘要

描述了一种完整的电子系统，该系统适用于基于锁模激光器的兆赫兹频域时间分辨荧光仪器。该电路产生一个10MHz的信号，与锁模激光脉冲频率锁相，这是许多商业频率合成器所需的外部参考信号。该设备与能够进行频率调制以用于时间分辨荧光成像的超快门控增强型电荷耦合器件相机配合使用时特别有用。
