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。
激光晶体是固态激光器的核心。它们是光放大发生的媒介，产生激光束。在这篇全面指南中，我们深入探讨激光晶体的世界。
On top of that, some overall flexibility is misplaced in experiments if a single are unable to Check out absorbers with various thickness or doping concentration, by way of example, without having exchanging the laser crystal by itself.
Which geometry, dopant and doping concentration on the achieve medium are most useful depend on many variables. The out there pump resource (kind of laser diode or lamp) along with the envisaged pumping arrangement are very important variables, but the material alone also has some affect. As an example, titanium–sapphire lasers have to be pumped with significant intensities, for which the form of a transversely cooled rod, operated with rather modest pump and laser beam diameter, is more ideal than e.

Naturally, it's very attractive that a given crystal quality is made continuously, although various laser styles can have a unique sensitivity to content parameters.
g. a thin disk. As A different example, Q-switched lasers reach a higher inhabitants density within the upper laser degree and they are for that reason extra delicate to quenching outcomes and Power transfer processes; thus, a reduce doping density is frequently appropriate for these products. For high-electric power lasers, lessen doping densities are often used to Restrict the density of warmth era, Despite the fact that slim-disk lasers operate greatest with really doped crystals. Quite a few laser merchandise don't get to the entire efficiency probable mainly because these kinds of specifics have not been adequately worked out.
Laser modeling and simulation can be employed to reliably ascertain the the best possible crystal Proportions, more info doping density And perhaps values of additional 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。
It is obvious that unique programs cause pretty distinct requirements on laser get media. For this reason, a broad vary of different crystals are employed, and earning the best choice is important for setting up lasers with ideal efficiency.

The medium should have a substantial transparency (reduced absorption and scattering) from the wavelength locations of pump and laser radiation, and fantastic optical homogeneity. To some extent, this will depend on the quality of the material, determined by specifics of your fabrication procedure.
Utilizing our advertising and marketing deal, you'll be able to Screen your logo, further more beneath your solution description, and these will been viewed by several photonics pros.
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。
