Different crystalline elements are certainly various relating to their hardness along with other Houses, which figure out with which procedures and how simply they may be cut and polished with good 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 just a means to fix the laser-Energetic ions at specified positions in Place. Many properties of the host materials are essential:
This is straightforward to try and do: just discover the lock icon before the URL while in the deal with bar and drag that for the bookmark toolbar Together with the mouse. In the event you find the bookmark entry as well lengthy, you are able to correct-click it to edit the textual content, e.g. working with "RP Enc" in place of "RP Photonics Encyclopedia".
For quasi-3-degree laser acquire media and even a few-stage obtain media, 1 often really should Restrict the length to a worth that's also short for economical pump absorption, as reabsorption results would otherwise spoil the general performance. For aspect pumping, extra criteria arrive into play; Moreover effective pump absorption, it is important to get a suitable spatial form of your obtain profile.
g. a thin disk. As One more case in point, Q-switched lasers achieve the next population density while in the higher laser level and therefore are hence additional sensitive to quenching results and Electrical power transfer processes; as a result, a decreased doping density is commonly appropriate for these gadgets. For prime-electric power lasers, lower doping densities are frequently accustomed to Restrict the density of warmth technology, although thin-disk lasers perform ideal with remarkably doped crystals. Lots of laser goods usually do not reach the total functionality probable mainly because these types of aspects haven't been thoroughly labored out.
GWU-Lasertechnik has more than thirty yrs of knowledge in distributing laser crystals. Pick GWU to take advantage of our wide awareness and in-field practical experience!
A high problems threshold when it comes to pulse fluence or peak depth may be significant for high-Strength amplifiers.
作为工业上使用较多的都是高掺钇铝石榴石，也就是说掺入不同的元素来达到不同的效果；作为工业激光，关注以下性能：
Which geometry, dopant and doping focus from the achieve medium are most useful depend on numerous components. The accessible pump supply (form of laser diode or lamp) and the envisaged pumping arrangement are essential variables, but the fabric alone also has some impact. For example, titanium–sapphire lasers need to be pumped with substantial intensities, for which the shape of the transversely cooled rod, operated with rather small pump and laser beam diameter, is more suitable than e.
It might be oriented for around perpendicular incidence on the laser beam, or at Brewster's angle. It could be fastened in certain stable mount which also functions for a warmth sink. Much larger crystals tend to be useful for more info facet pumping e.g. with significant-electric power diode bars.
The most common laser-active scarce earth ions and host media along with some normal emission wavelengths are proven in the following desk:
A couple of laser crystal elements have already been shown exactly where some saturable absorber substance is incorporated for passive Q switching of a laser.
Needless to say, it is vitally desirable that a provided crystal excellent is produced regularly, Despite the fact that distinctive laser designs can have a distinct sensitivity to substance parameters.
You can find a wide range of crystalline media, which can be grouped according to important atomic constituents and crystalline structures. Some crucial groups of crystals are:
蓝宝�?柱面�?球罩 偏振�?棱镜 红外光学元件 反射�?光学窗口 非球面镜 波片 分光�?制造能力

Laser crystals are optical crystals �?normally one crystals (monocrystalline optical materials) �?that happen to be made use of as obtain media for stable-point out lasers. Generally, They can be doped with possibly trivalent rare earth ions or transition steel ions.
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。
