We present a flat-top laser beam generation scheme using coherent beam combining of hexagonally arranged Gaussian lasers. To produce a beam with a flat-top profile, we optimize the amplitude and phase of each unit laser using the least-square method. Simulation results show that with 13 unit lasers, a beam with the flatness of less than 1% in the optimizing region can be achieved. The main lobe contains over 95% of the total power. The scheme requires no external beam shaping element and has the potential to be designed for high-power applications.

Different types of femtosecond optical tweezers have become a powerful tool in the modern biological field. However, how to control the irregular targets, including biological cells, using femtosecond optical tweezers remains to be explored. In this study
提出了一种基于颜色恒常性的图像背景虚化算法。首先,利用颜色恒常性检测图像中的光照情况,构建朗伯表面模型。然后,计算最大遮蔽物像素差值与最大局部像素差值,并利用软抠图算法获取图像深度图,对其进行灰度值分割,得到图片的前景与背景部分。最后,利用高斯滤波对图像的背景进行虚化处理。本方法能准确获取单目图像的前景与背景图像,且虚化效果明显。

1.55 μm波段是光通讯的一个重要波段,而且对人眼安全,有高的大气透过率,因此可以广泛应用于通讯和遥感测距等领域。由于Er3 离子对商品化的InGaAs激光二极管的抽运波长不能有效吸收,因此一般通过在基质中共掺杂Yb3 和Er3 离子来获得1.55 μm波段激光输出。采用助熔剂法生长了不同Yb3 和Er3 掺杂浓度的YAl3(BO3)4(YAB)晶体。运用速率方程模型研究了晶体中Yb3 到Er3 能量传递过程,得到了根据Yb3 离子的荧光寿命计算能量传递系数的简单计算公式。计算了不同掺杂离子浓度的YAB
