A high power narrow-linewidth nanosecond all-fiber laser based on the master oscillator power amplifier (MOPA) configuration is demonstrated. A pulsed seed with high repetition rate of 10 MHz was generated by modulating a continuous-wave (CW) single-frequ
本文首次报道了40mm孔径Nd:YAG片状激光器的激光特性.理论分析表明这类器件可望获得千瓦级激光平均功率.
深度学习在人脸识别的研究和应用中取得一定成效,但因计算量大且耗时,不适用于小型嵌入式设备。基于融合梯度特征的轻量级卷积神经网络SqueezeNet提取人脸特征,既能保证该网络模型适用于内存相对小的嵌入式设备,又能保证获得的人脸特征对不同光照更具鲁棒性。实验结果表明,将8×8分块图像中提取的一阶梯度特征,与轻量级卷积神经网络提取的全局特征相融合的人脸识别算法,在LFW数据集中识别率可达97.28%,
Experimental implementations of continuous optical time domain Fourier transformation based on time lenses and optical orthogonal frequency-division multiplexing (OFDM) system are carried out. Such a system is verified through 100-km transmission of 10-Gb
This Letter is concerned with the influence of polarization on the damage performance of type I doubler potassium dihydrogen phosphate crystals grown by the conventional growth method under 532 nm pulse irradiation. Pinpoint density (ppd) and the size dis
报告了掺氧LiF晶体中F2 心稳定性的实验研究,讨论了F2 心的衰减及其受氧稳定的机理。实验结果表明,LiF晶体中F2 心的衰减过程为二级反应。掺氧LiF与未掺氧者相比,F2 心衰减反应的激活能大约提高0.2电子伏,而速率常数则显著变小。最后给出了这两种晶体中的F2 心的结合能之差及电子亲和能之差的理论估计值。

提出了一种对大尺寸样品实现大范围、高分辨的原子力显微镜(AFM)扫描成像的新方法,并建立了相应的软硬件检测系统及装备。该方法设计了独特的AFM扫描成像探头。采用全新的光点跟踪探测光路实现了大范围高精度的纵向反馈控制和横向扫描成像,同时设计了开放式的样品台和微探针扫描结合步进电机移动的扫描方式,可对大尺寸(最大可达300 mm×300 mm),大重量(0~20 kg)样品表面进行微纳米扫描检测。利用该型AFM系统对实际样品进行扫描,获得了大范围(1 μm×1 μm~20 μm×20 μm)高分辨(横向分辨率
Tip-enhanced Raman scattering (TERS) spectroscopy is a nondestructive and label-free molecular detection approach that provides high sensitivity and nanoscale spatial resolution. Therefore, it has been used in a wide array of applications. We demonstrate
