Laser modeling and simulation can be employed to reliably determine the optimum crystal dimensions, doping density And maybe values of supplemental 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 much more than simply a way to repair the laser-Lively ions at certain positions in Place. Numerous Houses with the host material are essential:
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 acquire media or maybe three-degree get media, a single often really should limit the duration to a price which happens to be much too limited for efficient pump absorption, as reabsorption results would if not spoil the effectiveness. For side pumping, more factors occur into play; In addition to efficient pump absorption, it is important to obtain an acceptable spatial condition on the obtain profile.

A higher damage threshold in terms of pulse fluence or peak depth might be critical for high-energy 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 in the vicinity of perpendicular incidence from the laser beam, or at Brewster's angle. It could be mounted in a few solid mount which also acts being a heat sink. Larger sized crystals are generally useful for aspect pumping e.g. with significant-electrical power diode bars.
The most common laser-Lively exceptional earth ions and host here media along with some typical emission wavelengths are revealed in the subsequent desk:
Those surfaces that happen to be handed because of the laser beam are Ordinarily possibly oriented at Brewster's angle or have an anti-reflection coating.
For various factors, composite crystals have become well known. These Have got a spatially different chemical composition and will be built with special styles.
There is certainly a wide range of crystalline media, which may be grouped in accordance to special atomic constituents and crystalline structures. Some significant teams of crystals are:

GWU gives all widespread laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and many others.) that has a wide a number of technical specs. Aside from the properly-proven components, modern crystals with fantastic Qualities like Yb:CALGO can open up new horizons for demanding laser programs. Regardless of whether or not unique items for R & D purposes are demanded or Value-successful quantities in tiny, medium or big batches with in-time delivery for the output line are wanted: GWU’s committed support helps you to find the best core components for the software.
Laser crystals are optical crystals �?usually solitary crystals (monocrystalline optical components) �?that are made use of as get media for reliable-state lasers. Most often, They can be doped with possibly trivalent exceptional 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。
