Distinctive crystalline materials are quite various concerning their hardness along with other Homes, which decide with which strategies And exactly how very easily they can be Slash and polished with high quality.
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。
The host crystal is far more than simply a method to repair the laser-Lively ions at certain positions in Room. Many properties on the host substance are crucial:
This is straightforward to perform: just find the lock icon in front of the URL within the address bar and drag that into the bookmark toolbar with the mouse. Just in case you locate the bookmark entry far too long, you'll be able to right-simply click it to edit the text, e.g. utilizing "RP Enc" in lieu of "RP Photonics Encyclopedia".
For quasi-3-level laser achieve media or maybe 3-amount attain media, a single frequently must limit the duration to a value which happens to be as well limited for efficient pump absorption, as reabsorption results would otherwise spoil the effectiveness. For side pumping, further factors come into Perform; Aside from economical pump absorption, it is necessary to acquire an acceptable spatial condition from the obtain profile.

These tables incorporate only the most common host crystals; quite a few Other individuals exist, that happen to be less usually utilised.
Listed here you are able to post inquiries and feedback. In terms of they get recognized via the author, they are going to appear click here earlier mentioned this paragraph along with the creator’s respond to. The creator will choose acceptance dependant on particular requirements. Basically, The difficulty needs to be of adequately wide interest.
Some laser crystal elements have already been shown where by some saturable absorber materials is integrated for passive Q switching of a laser.
For many reasons, composite crystals have gotten popular. These Use a spatially different chemical composition and will be made with special styles.
激光晶体（laser crystal），可将外界提供的能量通过光学谐振腔转化为在空间和时间上相干的具有高度平行性和单色性激光的晶体材料。是晶体激光器的工作物质。
