Laser modeling and simulation may be used to reliably ascertain the ideal crystal dimensions, 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 medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions as well as the upper-state lifetime.
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-a few-stage laser get media or maybe 3-level gain media, a person normally ought to limit the length to a worth and that is way too quick for efficient pump absorption, as reabsorption consequences would usually spoil the functionality. For side pumping, supplemental things to consider arrive into play; Moreover effective pump absorption, it is important to acquire a suitable spatial shape with the acquire profile.
g. a skinny disk. As another instance, Q-switched lasers reach a better inhabitants density inside the higher laser amount and therefore are hence much more delicate to quenching consequences and Vitality transfer procedures; therefore, a reduced doping density is frequently suitable for these gadgets. For prime-ability lasers, reduced doping densities in many cases are utilized to limit the density of heat era, While slender-disk lasers work greatest with hugely doped crystals. Lots of laser products don't reach the entire performance possible since these kinds of facts haven't been thoroughly labored out.
GWU-Lasertechnik has a lot more than 30 many years of encounter in distributing laser crystals. Choose GWU to take pleasure in our large knowledge and in-industry working experience!
A high injury threshold concerning pulse fluence or peak depth could be important 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：

It might be oriented for near perpendicular incidence of your laser beam, or at Brewster's angle. It could be mounted in certain reliable mount which also acts as being a warmth sink. Much larger crystals usually are employed for facet pumping e.g. with substantial-electric power diode bars.
The most common laser-Lively unusual earth ions and host media together with some usual emission wavelengths are revealed in the subsequent table:
A handful of laser crystal products are actually shown in which some saturable absorber material is incorporated for passive Q switching of the laser.
For several good reasons, composite crystals have gotten well-known. These Possess a spatially varying chemical composition and can be produced with Unique 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。

GWU offers all frequent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and many others.) with a wide a number of specifications. Besides the properly-founded materials, revolutionary crystals with superb properties like Yb:CALGO can open up new horizons for demanding laser purposes. Regardless of no matter if specific click here pieces for R & D applications are expected or Value-effective numbers in small, medium or significant batches with in-time supply for your output line are required: GWU’s focused services really helps to find the best Main elements to your application.
It is apparent that distinctive programs bring on very distinct necessities on laser attain media. Because of this, a broad range of different crystals are applied, and producing the right option is essential for constructing lasers with the best possible general performance.
