The commonest laser-Energetic exceptional earth ions and host media together with some standard emission wavelengths are proven in the next desk:

Which geometry, dopant and doping concentration in the achieve medium are most beneficial count on various factors. The accessible pump source (type of laser diode or lamp) and the envisaged pumping arrangement are crucial components, but the material alone also has some affect. As an example, titanium–sapphire lasers have to be pumped with superior intensities, for which the form of the transversely cooled rod, operated with comparatively little pump and laser beam diameter, is a lot more appropriate than e.

激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。
g. a thin disk. As A further example, Q-switched lasers attain a better populace density during the higher laser amount and they are consequently a lot more sensitive to quenching results and Vitality transfer procedures; therefore, a lower doping density is often suitable for these equipment. For top-electric power lasers, decreased doping densities will often be accustomed to limit the density of warmth technology, Even though thin-disk lasers work most effective with remarkably doped crystals. A lot of laser items don't get to the total overall performance potential mainly because this sort of details have not been thoroughly worked out.
Several laser crystal elements happen to be demonstrated where by some saturable absorber materials is integrated for passive Q switching of a laser.
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 apparent that different applications lead to very distinctive prerequisites on laser attain media. Due to this, a broad vary of various crystals are check here applied, and earning the proper selection is essential for constructing lasers with the best possible effectiveness.
Distinct crystalline materials are certainly distinct about their hardness and also other properties, which establish with which methods And the way easily they are often Slice and polished with top quality.
The medium must have a high transparency (small absorption and scattering) while in the wavelength areas of pump and laser radiation, and excellent optical homogeneity. To some extent, this depends upon the standard of the material, based on details with the fabrication procedure.
