激光二极管

But at Drupa 2000, the machine was released with a 5mw laser diode, making the machine even more affordable.

但在德鲁巴2000年，机器被释放与5 mW激光二极管，使机器更经济实惠。

This means that although they are more focusable than a hand torch say, the size of spot they can be focused to is still relatively large, limiting their use.

但高能量的激光二极管不能产生完美的激光束，这意味着他们虽然比手电筒更有聚焦能力，它们能聚焦的光斑尺寸仍然相对很大，从而限制它们的用途。

Diode pumped monolithic nonplanar ring laser has the advantages of compactness, reliability and high efficiency.

激光二极管抽运的单块非平面环形腔固体激光器具有结构稳固、效率高等优点，在一定的纵向磁场作用下，可形成单向行波振荡，纵向抽运时就可得到较高功率的单频输出，有广泛的应用前景。

An integrated laser and optical modulator driver for ultra-high speed optic-fiber communication systems is designed and fabricated in a 0.2m gate length AlGaAs/InGaAs/GaAs pseudomorphic high electron mobility transistor process.

采用0.2m GaAs PHEMT工艺设计并实现了超高速光纤通信系统用激光二极管／调制器集成驱动器电路。

The idea is that the laser diode can be "pigtailed" with an optical fiber, therefore obviating the need for any focusing optics whatsoever.

该想法是，激光二极管可以& pigtailed &与光纤，因此，免却无需任何光学聚焦什么。

And only modulate the direction of the tensor d33 periodically. So QPM enlarge the application range of the crystal in existence. Presently diode pumped all-solid-state lasers have been developing quickly, which provides an ideal pump source for QPM.

近年来，随着激光二极管技术的发展，小功率全固态激光器已经十分成熟，为准相位匹配提供了优质的泵源，因此，小功率全固态激光器的准相位匹配频率变换成为目前的一个研究热点。

Based on the ring-shaped laser-diode array side-pumped Nd:YLF high gain amplifier and the conventional plan-concave resonator, a simple structure single-longitudinal-mode single-pulse Q-switched oscillator is demonstrated by taking advantages of mode-selecting property of passive Q-switches (Cr4+:YAG crystal) and etalons (formed by two end of uncoated Nd:YLF rod).

以激光二极管环形阵列侧面抽运Nd：YLF棒高增益放大器模块为基础，在经典的平凹驻波腔中加入一片Cr4+：YAG晶体作为被动Q开关，利用被动Q开关本身所具有的振荡选模功能以及两端不镀膜的Nd：YLF棒所具有的标准具效应，简便地实现了稳定的单脉冲、单纵模调Q输出。

As a result, it is difficult to measure the wavefronts of the laser beams by conventional wavefront sensors.

大功率激光二极管线阵特殊的发光区结构使它具有不理想的光学特性，特别是其快轴方向高达40°的大发散角，使得传统的波前探测器很难对其进行波前探测。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
