摘要

在本文中，我们提出了一种全反射 FROG 设备的新方案，该设备使用近 90° 的逆反射镜，可对超短激光脉冲的强度和相位进行完整的单次测量。所提出的装置有几个优点，例如：(1) 它是一个全反射装置，因此没有额外的材料色散；(2) 它操作简单，不受校准干扰；(3) 装置的时间分辨率和时间范围可根据要求进行调整。所提议的装置用于测量由钛蓝宝石激光振荡器产生的锁模超短激光脉冲。此外，还对通过 30 厘米长的掺钕玻璃棒获得的色散展宽激光脉冲进行了表征，并估算了玻璃棒的群速度色散参数值。

All reflective FROG using near 90° retro-reflecting mirror for single shot intensity and phase profile measurement of ultra-short laser pulse

In this paper, we propose a novel scheme for an all-reflective FROG device using a near-90° retro-reflecting mirror for the complete single-shot measurement of intensity and phase of ultra-short laser pulses. The proposed device has several advantages, such as (1) it is an all-reflective setup, hence no added material dispersion; (2) it is simple and free from alignment disturbances; and (3) the temporal resolution and temporal range of the device can be tuned as per requirement. The proposed device was set up to measure mode-locked ultra-short laser pulses generated from a Ti:Sapphire laser oscillator. Dispersion-broadened laser pulses, obtained by passing the oscillator pulses through a 30 cm long Nd:glass rod, were also characterized, and the group velocity dispersion parameter value of the glass rod was estimated.
