PD-LD激光二极管，VBG光栅技术产品

PD-LD是一家光电子公司，总部在美国新泽西州彭宁顿，主要生产并装配带尾纤或者带光纤插口的二极管激光器、LED、探测器、高功率的脉冲激光以及光纤通信中的双向装置。是新泽西州发展快的技术性公司，PD-LD公司同时也生产客户定制的VBG零件，以及在拉曼光谱，高功率激光，显示器等方面需要使用的内置VBG的激光。

PD-LD’s的有源器件和无源器件，无论标准的或定制的，总有器件能满足客户的产品要求，客户遍布光通讯，传感，自动化，航空，光谱学，医学工业等各个领域，且都为上述领域的领导者。PD-LD不仅仅只限于为芯片提供封装，而且拥有一些世界级的光学专家，他们拥有高深的专业知识，能满足客户提出的苛刻的定制要求。

PD-LD公司是VBG光栅技术的全球先驱，近刚刚获得一项新，可以使激光二极管结构更加简单，效率更加稳定。这项发明使用的VBG技术可以改善多种发光装置的输出特性，如激光器，激光二极管，发光二极管等。这项用来改进技术，并且已经广泛使用在拉曼光谱，激光泵浦以及光纤通信中。其中提供了一个修改或者改进激光输出光谱的方法。使用了一个特殊的光学元件提高激光的稳定性。

“这项新的发明使得PD-LD公司的数达到了14个，这也证明了我们在VBG领域的领导地位，立足在我们已有的基础上，在工业化以及应用方面，我们的数将不断增长。”PD-LD公司的总裁兼CEO弗拉基米尔博士如此说到。

PD-LD公司的输出波长为523nm或者785nm的新型拉曼激光光源，采用光纤耦合输出，通过使用PD-LD公司专有的VBG-stabilized的808nm激光器，泵浦倍频到532nm的YAG晶体，实现了50mW的输出功率。 该光源具有窄线宽、高功率、紧凑及牢固的设计，使其特别适用于便携仪器应用。其小巧的外形和简单的接口使其成为工业、军事和应用的理想选择。还推出了TO封装光源，激光芯片被密封在TO-9或者TO-56中，整个TO结构整合在一个铜质的散热器中，以达到光学特性。出光口安装了非球面棱镜以及PD-LD公司的VBG，对光路进行压缩，并且得到窄带激光，是拉曼光谱的理想光源。在原先LML-785.0RB-XX的基础上，通过改变制冷方式，使得光源盒可以在-15摄氏度至50摄氏度的环境中工作，由此衍生出新的型号LML-785.0CB-XX。新款的产品同样继承了上代产品的紧凑型外观，只有76*64*17mm的大小，在这么大的体积上整合了5V的电压输入，可编程的USB等接口，光输出通过一个FC/APC接口耦合到光纤中，使用十分便捷。

VBG wavelength stabilization of high power laser diodes and laser diode arrays

Another major application of VBG technology is the wavelength stabilization of high power laser diodes and laser diode arrays, e.g., for more efficient pumping of solid state lasers and fiber lasers. Some dramatic improvements have been achieved:

Narrow line width, < 0.5 nm
Precise center wavelength control, +/- 0.5 nm
Reduced thermal drift, ~0.01 nm/C
