EMP control and characterization on high-power laser systems ... , which produce radiation across a wide band from DC to terahertz frequencies. Improved understanding and control of EMP is vital as we enter a new era of high repetition rate, high intensity lasers (e.g. the Extreme Light Infrastructure). We present rec
A platform for high-repetition-rate laser experiments on the Lar... We present a new experimental platform for studying laboratory astrophysics that combines a high-intensity, high-repetition-rate laser with the Large Plasma Device at the University of California, Los Angeles. To demonstrate the utility of this platform, ...
Optical property measurements of 235 mm large-scale Ti:sapphire ... A Ti:sapphire crystal with a diameter of 235 mm and thickness of 72 mm was grown by the heat exchange method (HEM). The absorption intensity of the crystal at 532 nm averaged at 91%. The figures of merit (FOMs) at different positions of the crystal were ...
Optically spatial information selection with hybridly polarized ... ... In this work, we study a polarization selection of spatial intensity distribution by utilizing a hybridly polarized beam as a ... Rb87 atom vapor. We experimentally observe that the spatial intensity distribution of the probe beam after passing through atoms ...
SER estimation method for 56 GBaud PAM-4 transmission system ... density function (GGPDF)-based method to estimate the symbol error ratio (SER) for pulse amplitude modulation (PAM-4) in an intensity modulation/direct detection (IM/DD) system. Furthermore, a closed form expression of SERGGD for PAM-4 has been derived. ...
Extracting cavity and pulse phases from limited data for coheren... ... to describe the optical interference process. An algorithm, extracting the cavity phase and pulse phases from limited data, where only the pulse intensity is available, is developed to diagnose optical cavity resonators. We also implement the algorit
Noise-sidebands-free and ultra-low-RIN 1.5 μm single-frequency f... A noise-sidebands-free and ultra-low relative intensity noise (RIN) 1.5 μm single-frequency fiber laser is demonstrated for the first time to our best knowledge. Utilizing a self-injection locking framework and a booster optical amplifier, the noise ...
Femtosecond laser-induced damage threshold in snow micro-structu... ... proposed. A notably increased proton energy was attributed to a combination of several mechanisms such as localized enhancement of the laser field intensity near the tip of $1~\unicode[STIX]｛x03BC｝\text｛m｝$ size whisker and increase in the hot electron ...
 基于AR模型的HIFU无损测温方法研究  自回归功率谱密度（AR-PSD）方法的基础是生物组织的离散散射体模型〔超声体模〕理论，该模型认为生物组织为半规则的散射体分布的，这种方法是基于温度和频移的相关特性。本文介绍超声回波信号对HIFU（High Intensity Focused Ultrasound）治疗的测温技术，从测温模型和算法，实验仪器的设计和构建，仿真和离体实验中获取了一套有效的测温方法，利用Matlab7.1和VC++6.0作为工具对超声回波信号进行计算机仿真，并从实验获得的超声回波 ...
