These tables incorporate only the commonest host crystals; several Many others exist, which can be less regularly applied.

These ions empower the crystal to amplify gentle with the laser wavelength by way of stimulated emission, when Power is equipped to your crystal by means of absorption of pump mild (�?optical pumping

Laser crystals are optical crystals �?commonly solitary crystals (monocrystalline optical elements) �?which are made use of as gain media for sound-condition lasers. Typically, They are really doped with either trivalent uncommon earth ions or transition metal ions.

激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。

The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions and in addition the higher-state life time.

A significant surface top quality is not surprisingly vital. Specifications of surface area flatness are sometimes much better than . This allows to prevent equally scattering losses and wavefront distortions which often can degrade the laser's beam high-quality. In addition, scratch and dig technical specs

g. a thin disk. As another example, Q-switched lasers arrive at here a better populace density from the higher laser stage and they are as a result extra delicate to quenching effects and Electrical power transfer procedures; for that reason, a lessen doping density is commonly appropriate for these equipment. For high-ability lasers, decreased doping densities in many cases are utilized to limit the density of heat technology, although slender-disk lasers function finest with hugely doped crystals. Quite a few laser solutions tend not to reach the complete efficiency potential mainly because these kinds of details have not been properly worked out.

The host crystal is way more than just a means to fix the laser-Lively ions at particular positions in Room. Many Qualities on the host product are crucial:

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 diverse apps bring on pretty different prerequisites on laser gain media. For this reason, a wide assortment of different crystals are made use of, and making the right option is important for developing lasers with ideal effectiveness.

For several good reasons, composite crystals are becoming well-known. These Use a spatially different chemical composition and can be created with special designs.

There's an array of crystalline media, which may be grouped in accordance to important atomic constituents and crystalline structures. Some crucial groups of crystals are:

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。
