This is not difficult to carry out: just find the lock icon in front of the URL inside the address bar and drag that for the bookmark toolbar Along with the mouse. Just in case you locate the bookmark entry much too extended, it is possible to correct-click it to edit the text, e.g. using "RP Enc" rather than "RP Photonics Encyclopedia".
激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。
Not surprisingly, it is rather desirable that a specified crystal good quality is created consistently, While distinct laser layouts can have a unique sensitivity to materials parameters.
The utmost probable doping concentration can rely strongly to the host materials and its fabrication system.
激光晶体的效率在很大程度上依赖于某些属性，这些属性不仅限于其基本组成。这些特性决定了产生的激光光束的质量和随后的应用。
热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。
For quasi-three-amount laser achieve media and even a few-degree gain media, a person typically must limit the size to a value and that is much too brief for effective pump absorption, as reabsorption consequences would if not spoil the efficiency. For facet pumping, more factors appear into Enjoy; Apart from efficient pump absorption, it is get more info important to obtain a suitable spatial shape with the acquire profile.
Different crystalline resources are extremely distinct about their hardness and also other properties, which establish with which strategies And exactly how effortlessly they are often Slash and polished with good quality.
GWU-Lasertechnik has more than 30 many years of experience in distributing laser crystals. Select GWU to take advantage of our extensive know-how and in-area expertise!
Making use of our promotion package deal, you could Show your brand, further under your product description, and these will been observed by quite a few photonics experts.
人造红宝石激光晶体是首次实现激光输出的材料。可用焰熔法、提拉法或助熔剂法生产单晶。用提拉法容易获得大尺寸优质晶体。
