A 1 550 nm long-wavelength vertical cavity surface emitting laser (VCSEL) on InP substrate is designed and fabri-cated. The transfer matrix is used to compute reflectivity spectrum of the designed epitaxial layers. The epitaxial layers mainly consist of 40 pairs of n-AlxGayIn(1-x-y)As/InP, and 6 strain compensated AlxGayIn(1-x-y)As/InP quantum wells on n-InP substrate, respectively. The top distributed Bragg reflection (DBR) mirror system has been formed by fabricat-ing 4.5 pairs of SiO2/Si. The designed cavity mode is around 1 536 nm. The dip of the fabricated cavity mode is around 1 530 nm. The threshold current is 30 mA and the maximum output power is around 270 μW under CW opera-tion at room temperature.

图像语义分割作为一种像素级分类技术,已应用于合成孔径雷达(SAR)图像的解译领域中。U-Net是一种端到端的图像语义分割网络,具有典型的编码-解码结构。其中,编码部分主要由卷积层和池化层组成,可以有效提取图像中的目标特征,但难以获取目标的位置和方向等信息。胶囊网络是一种能够获取目标姿态(位置、大小、方向)等信息的神经网络,因此,提出了一种基于U-Net和胶囊网络的SAR图像语义分割方法。此外,考虑到SAR图像数据集较小的特点,将U-Net的编码部分设计成视觉几何组(VGG16)结构,将预训练的VGG16模

本文理论计算了用圆锥管内多次全反射激光而产生的多普勒频移来冷却原子束的机制。给出了最佳冷却原子束的圆锥管的夹角、长度、反射次数及激光入、出射角等参数。理论计算了原子束经过圆锥管冷却的速度分布情况。数值计算结果表明:采用两个长130 cm的锥形管来冷却原子束,选用合适的失谐量可使极大部分速度小于1200 m/s的原子冷却到8 lm/s,并且可得到单一速度的高亮度的原子束。
本文论述了在各种参量大范围变化下后混合型CO2气动激光器的增益系数的实验研究。把(CO2 He)混合到用拉伐耳喷嘴快速膨胀而致冷的N2超声流中,便能得到粒子数反转。发现增益系数依赖于离混合孔的距离和(CO2 He)的流量。随着(CO2 He)流量的增加,增益系数线性地增加,而对应于最大增益系数的离孔距离缩短。观测到增益为正的区域沿流动轴延伸约30厘米,在离孔111毫米的顺流处,最大增益是0.8米-1。根椐沿流动轴的压力和流速的测量,对增益系数进行了分析。
