These ions empower the crystal to amplify mild at the laser wavelength by means of stimulated emission, when Power is provided into the crystal by way of absorption of pump mild (�?optical pumping

为了使激光器有效运作，需要有效管理运行过程中产生的热量。具有良好热导率的激光晶体可以更有效地散热，防止热透镜效应或断裂。

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 of the gain medium are most useful rely on a number of aspects. The out there pump supply (variety of laser diode or lamp) as well as the envisaged pumping arrangement are important variables, but the fabric alone also has some influence. By way of example, titanium–sapphire lasers need to be pumped with significant intensities, for which the form of the transversely cooled rod, operated with fairly modest pump and laser beam diameter, is much more ideal than e.

A high floor top quality is of course crucial. Specs of floor flatness will often be better than . This aids to prevent each scattering losses and wavefront distortions which may degrade the laser's beam quality. Furthermore, scratch and dig specs

g. a thin disk. As One more example, Q-switched lasers attain a better population density while in the higher laser degree and they are therefore more delicate to quenching effects and Electricity transfer processes; as a result, a reduced doping density is frequently appropriate for these units. For top-electric power lasers, reduce doping densities will often be accustomed to limit the density of warmth generation, although skinny-disk lasers operate best with hugely doped crystals. Lots of laser goods do not get to the entire performance prospective mainly because such details haven't been properly labored out.

Some laser crystal supplies are demonstrated where by some saturable absorber content is included for passive more info 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。

For quasi-a few-amount laser acquire media or even 3-stage obtain media, a person often needs to limit the size to a worth and that is as well brief for successful pump absorption, as reabsorption effects would in any other case spoil the effectiveness. For aspect pumping, additional criteria come into Enjoy; Other than successful pump absorption, it is vital to obtain a suitable spatial shape of your acquire 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。
