Laser modeling and simulation may be used to reliably identify the ideal crystal Proportions, doping density And maybe values of more 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 a lot more than simply a means to repair the laser-Lively ions at specified positions in space. Many Homes on the host substance are important:
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。
For quasi-3-level laser gain media or even a few-degree gain media, a person generally has to Restrict the size to a worth which can be too small for economical pump absorption, as reabsorption outcomes would otherwise spoil the functionality. For side pumping, supplemental issues occur into Perform; Other than effective pump absorption, it can be crucial to obtain a suitable spatial form in the achieve profile.
g. a thin disk. As One more case in point, Q-switched lasers arrive at a higher inhabitants density in the higher laser stage and so are consequently much more delicate to quenching consequences and Electrical power transfer processes; for that reason, a reduced doping density is usually suitable for these equipment. For high-energy lasers, lessen doping densities are often utilized to Restrict the density of heat era, While thin-disk lasers perform ideal with remarkably doped crystals. Many laser solutions tend not to get to the full overall performance possible for the reason that this kind of information haven't been appropriately labored out.

A higher destruction threshold concerning pulse fluence or peak depth could be significant for high-Electricity 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：

These tables have only the most typical host crystals; many Some others exist, which are less commonly employed.
The most typical laser-Energetic uncommon earth ions and host media together with some common emission wavelengths are shown in the subsequent desk:
Some laser crystal supplies are already shown where some saturable absorber materials is integrated for passive Q switching of the laser.
For many good reasons, composite crystals have become well-known. These Use a spatially various chemical composition and might be designed with Distinctive 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。
With That idea, 1 would not require a further saturable absorber crystal, to ensure that a single could make a lot more compact Q-switched laser setups with reduced interior parasitic losses. On the other hand, undesired side effects might also take place, for instance getting undesired valence states with the associated ions or Electrical power transfers.
GWU offers all prevalent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and many others.) by using a broad number of specifications. Apart from the effectively-established elements, impressive crystals with exceptional Homes like Yb:CALGO can open new horizons for demanding laser programs. Despite regardless of whether unique pieces for R & D needs are demanded or Expense-successful quantities in little, medium or massive batches with in-time website supply for your creation line are required: GWU’s focused support really helps to find the finest core factors on your software.
It is obvious that unique applications cause very distinctive prerequisites on laser obtain media. Due to this, a wide range of various crystals are utilized, and earning the correct preference is important for constructing lasers with optimum efficiency.
