Laser modeling and simulation can be used to reliably establish the ideal crystal Proportions, doping density And perhaps values of additional parameters.
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 way more than just a means to fix the laser-active ions at selected positions in House. Quite a few Attributes on the host product are crucial:
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。
The utmost achievable doping concentration can rely strongly around the host material and its fabrication method.

(For those who afterwards retract your consent, We are going to delete People inputs.) As your inputs are very first reviewed through the author, they may be posted with a few delay.
GWU-Lasertechnik has much more than thirty several years of knowledge in distributing laser crystals. Pick GWU to take advantage of our broad knowledge As well as in-discipline encounter!
A large damage threshold with regard to pulse fluence or peak intensity is often crucial for prime-Power 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 concentration from the achieve medium are most useful rely on various factors. The obtainable pump supply (variety of laser diode or lamp) as well as the envisaged pumping arrangement are very important components, but the fabric itself also has some influence. By way of example, titanium–sapphire lasers should be pumped with superior intensities, for which the form of a transversely cooled rod, operated with comparatively modest pump and laser beam diameter, is much more ideal than e.
It could be oriented for near perpendicular incidence from the laser beam, or at Brewster's angle. It may be mounted in a few reliable mount which also acts being a warmth sink. More substantial crystals usually are useful for facet pumping e.g. with significant-electric power diode bars.
The most typical laser-Energetic unusual earth ions and host media together with some typical emission wavelengths are revealed in the next table:
Those surfaces which might be passed because of the laser beam are Typically possibly oriented at Brewster's angle or have an anti-reflection coating.
Certainly, it is extremely appealing that a supplied crystal quality is made continually, although various laser types may have another sensitivity to material parameters.
There is certainly a wide array of crystalline media, that may be grouped in accordance to big atomic constituents and crystalline buildings. Some vital teams of crystals are:
With that concept, a single isn't going to will need yet another saturable absorber crystal, to make sure that one may make much more compact Q-switched laser setups with reduce internal parasitic losses. Nevertheless, unwanted side effects might also occur, for example acquiring undesirable valence states in the involved ions or energy transfers.
GWU delivers all frequent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so on.) with a wide assortment of specs. In addition to the well-founded resources, progressive crystals with excellent Attributes like Yb:CALGO can open new horizons for demanding laser applications. It doesn't matter no matter if personal parts for R & D needs are needed or Price tag-successful numbers in smaller, medium or big batches with in-time supply for your output line are necessary: GWU’s focused support really helps to find the ideal Main elements in your application.
It is apparent that various apps produce very distinct necessities on laser attain media. For this Nonlinear Crystal reason, a broad assortment of various crystals are applied, and making the best option is essential for constructing lasers with optimum functionality.
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。
