Laser crystals are optical crystals �?normally single crystals (monocrystalline optical products) �?which can be utilized as get media for strong-condition lasers. Most often, They may be doped with both trivalent scarce earth ions or changeover metal ions.

Additionally, some versatility is dropped in experiments if just one are unable to Check out absorbers with diverse thickness or doping focus, by way of example, without the need of exchanging the laser crystal by itself.

Which geometry, dopant and doping focus in the gain medium are most beneficial depend upon many factors. The available pump resource (variety of laser diode or lamp) and the envisaged pumping arrangement are essential factors, but the fabric alone also has some influence. Such as, titanium–sapphire lasers need to be pumped with high intensities, for which the form of the transversely cooled rod, operated with relatively modest pump and laser beam diameter, is more ideal than e.

晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。

A higher surface good quality is not surprisingly vital. Specifications of area flatness are often better than . This assists to prevent each scattering losses and wavefront distortions which can degrade the laser's beam quality. On top of that, scratch Laser Crystal and dig requirements

The most achievable doping focus can depend strongly about the host product and its fabrication approach.

Laser modeling and simulation can be used to reliably identify the ideal crystal Proportions, doping density And perhaps values of more parameters.

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。

For quasi-a few-amount laser get media or maybe 3-level attain media, 1 normally should limit the duration to a price which is far too quick for economical pump absorption, as reabsorption results would if not spoil the effectiveness. For side pumping, further criteria arrive into Engage in; Other than effective pump absorption, it can be crucial to obtain a suitable spatial form on the attain profile.

主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。

The medium should have a high transparency (very low absorption and scattering) inside the wavelength locations of pump and laser radiation, and very good optical homogeneity. To some extent, this is dependent upon the caliber of the fabric, determined by facts in the fabrication system.

With that concept, a single doesn't require an additional saturable absorber crystal, so that one may perhaps make additional compact Q-switched laser setups with lessen inside parasitic losses. Nonetheless, unwanted side effects could also arise, such as acquiring unwanted valence states on the involved ions or Electricity transfers.

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。
