Abstract

We demonstrate a high-performance ultrafast broadband time-resolved photoluminescence (TRPL) system based on the transient grating photoluminescence spectroscopy (TGPLS) technique. The core of the system is a Kerr effect-induced transient grating (TG) optical gate driven by high repetition rate ultrashort laser pulses at 1030 nm with micro-Joule pulse energy. Satisfying the demands of spectroscopy applications, the setup achieves high sensitivity, rapid data acquisition, ultrafast time resolution, and a wide spectral window from ultraviolet to near-infrared. The time resolution can be further improved to achieve <80 fs instrument response function by employing the multiple plate compression (MPC) technique to temporally compress the driving pulses. This work presents a new benchmark for ultrafast TRPL.

新一代超快光致发光光谱：瞬态光栅光门与先进飞秒激光技术的集成

研究了一种基于瞬态光栅光致发光光谱（TGPLS）技术的高性能超快宽带时间分辨光致发光（TRPL）系统。该系统的核心是一个克尔效应诱导的瞬态光栅（TG）光门，由1030 nm高重复频率的超短激光脉冲以微焦耳脉冲能量驱动。该装置满足了光谱应用的需求，具有高灵敏度、快速数据采集、超快时间分辨率和从紫外到近红外的宽光谱窗口。采用多板压缩（MPC）技术对驱动脉冲进行时间压缩，可进一步提高时间分辨率，达到80 fs的仪器响应功能。这项工作为超快TRPL提供了一个新的基准。

期刊介绍： The Journal of Physical Chemistry (JPC) Letters is devoted to reporting new and original experimental and theoretical basic research of interest to physical chemists, biophysical chemists, chemical physicists, physicists, material scientists, and engineers. An important criterion for acceptance is that the paper reports a significant scientific advance and/or physical insight such that rapid publication is essential. Two issues of JPC Letters are published each month.
