The most common laser-Energetic exceptional earth ions and host media together with some typical emission wavelengths are demonstrated in the following desk:

激光晶体的极化性能可能会影响输出激光束的质量和特性。有些激光晶体产生线性偏振光，这对某些应用可能有益。

芯飞睿所有的服务和支持都立足于使我们的客人工作的更加高效，更有价值。

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。

Which geometry, dopant and doping focus from the obtain medium are most advantageous rely on a number of elements. The accessible pump source (variety of laser diode or lamp) as well as envisaged pumping arrangement are very important aspects, but the fabric itself also has some impact. Such as, titanium–sapphire lasers should be pumped with large intensities, for which the form of the transversely cooled rod, operated with relatively smaller pump and laser beam diameter, is much more correct than e.

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。

A superior surface good quality is certainly essential. Specs of surface area flatness in many cases are much better than . This allows to prevent equally scattering losses and wavefront distortions which often can degrade the laser's beam high-quality. On top of that, scratch and dig technical specs

g. a thin disk. As another instance, Q-switched lasers arrive at the next population density from the higher laser degree and so are hence much more sensitive to quenching outcomes and Electrical power transfer procedures; for that reason, a decreased doping density is commonly suitable for these devices. For high-energy lasers, reduced doping densities in many cases are accustomed to Restrict the density of heat era, Though skinny-disk lasers Laser Crystal perform greatest with very doped crystals. Numerous laser goods don't get to the full performance opportunity for the reason that these specifics haven't been appropriately labored out.

The host crystal is considerably more than simply a means to fix the laser-active ions at specified positions in Place. Many Homes of your host materials are very important:

激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。

It is clear that distinct apps bring on pretty distinctive requirements on laser acquire media. For this reason, a broad range of various crystals are made use of, and earning the ideal preference is important for constructing lasers with optimum general performance.

Distinct crystalline elements are quite various about their hardness and also other Qualities, which identify with which strategies And exactly how conveniently they can be cut and polished with good quality.

The medium ought to have a high transparency (low absorption and scattering) from the wavelength regions of pump and laser radiation, and very good optical homogeneity. To some extent, this depends upon the caliber of the material, based on details on the fabrication system.

With that concept, 1 doesn't want an extra saturable absorber crystal, in order that a single might make much more compact Q-switched laser setups with lower interior parasitic losses. On the other hand, undesirable Unwanted effects could also arise, like getting undesired valence states on the involved ions or Power transfers.
