Laser modeling and simulation can be used to reliably figure out the optimum crystal dimensions, doping density And perhaps values of more parameters.
The medium ought to have a superior transparency (low absorption and scattering) in the wavelength locations of pump and laser radiation, and very good optical homogeneity. To some extent, this is dependent upon the caliber of the material, based on specifics with the fabrication process.
The host crystal is much more than simply a means to repair the laser-active ions at specified positions in space. A number of Houses of 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 maximum doable doping focus can count strongly around the host substance and its fabrication process.
g. a thin disk. As An additional instance, Q-switched lasers achieve a better population density while in the higher laser stage and so are therefore much more delicate to quenching effects and Vitality transfer procedures; thus, a lower doping density is often suitable for these products. For high-energy lasers, lower doping densities in many cases are used to limit the density of heat generation, Despite the fact that slender-disk lasers perform finest with really doped crystals. Numerous laser goods do not get to the full functionality prospective for the reason that these aspects have not been effectively worked out.

A superior destruction threshold in terms of pulse fluence or peak depth is usually significant for prime-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：

These tables consist of only the most common host crystals; lots of others exist, which happen to be fewer routinely employed.
The most common laser-Energetic unusual earth ions and host media along with some common emission wavelengths are demonstrated in the following table:
A handful of laser crystal elements have already been demonstrated exactly where some saturable absorber product is incorporated for passive Q switching of a laser.
Obviously, it is extremely desirable that a supplied crystal excellent is generated continually, Despite the fact that diverse laser designs might have another sensitivity to material parameters.
There's a wide range of crystalline media, which can be grouped in accordance to special atomic constituents and crystalline constructions. Some crucial groups of crystals are:
With that concept, a single will not have to have a further saturable absorber crystal, to ensure a single might make extra compact Q-switched laser setups with decrease internal parasitic losses. Having said that, undesirable Negative effects might also arise, like acquiring unwelcome valence states of the concerned ions or energy transfers.
GWU gives all prevalent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so forth.) having a broad range of technical specs. Apart from the properly-established components, modern crystals with superb Qualities like Yb:CALGO can open up new horizons for demanding laser applications. It doesn't matter no matter whether unique parts for R & D purposes are necessary or Price-productive quantities in tiny, medium or large batches with in-time supply for your output line are required: GWU’s committed service helps you to locate the more info best Main components in your software.
It is obvious that diverse applications produce really diverse demands on laser gain media. For that reason, a broad assortment of various crystals are employed, and earning the right alternative is essential for developing lasers with optimum performance.
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。
