Distinctive crystalline elements are incredibly distinct regarding their hardness as well as other Attributes, which identify with which procedures And just how quickly they can be cut and polished with good quality.
人造红宝石激光晶体是首次实现激光输出的材料。可用焰熔法、提拉法或助熔剂法生产单晶。用提拉法容易获得大尺寸优质晶体。
The host crystal is much more than simply a way to fix the laser-Lively ions at selected positions in space. A number of Attributes from the host substance are essential:
This is straightforward to try and do: just discover the lock icon in front of the URL within the deal with bar and drag that to your bookmark toolbar With all the mouse. In the event you find the bookmark entry as well extensive, you'll be able to correct-simply click it to edit the text, e.g. utilizing "RP Enc" rather than "RP Photonics Encyclopedia".
The most probable doping concentration can count strongly within the host substance and its fabrication method.

A substantial destruction threshold regarding pulse fluence or peak depth is usually crucial for prime-Electricity amplifiers.
作为工业上使用较多的都是高掺钇铝石榴石，也就是说掺入不同的元素来达到不同的效果；作为工业激光，关注以下性能：
Which geometry, dopant and doping focus from the achieve medium are most advantageous depend on several aspects. The obtainable pump source (kind of laser diode or lamp) and also the envisaged pumping arrangement are important factors, but the fabric alone also has some affect. For instance, titanium–sapphire lasers must be pumped with higher intensities, for which the shape of a transversely cooled rod, operated with reasonably tiny pump and laser beam diameter, is more correct than e.
These tables comprise only the most typical host crystals; many Other folks exist, which are considerably less routinely used.
The commonest laser-active unusual earth ions and host media along with some normal emission wavelengths are shown in the subsequent desk:
A couple of laser crystal elements happen to be demonstrated wherever some saturable absorber materials is integrated for passive Q switching of the laser.
For various motives, composite crystals are getting Laser Crystal to be well known. These have a spatially various chemical composition and may be designed with special shapes.
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。
With that concept, just one won't want a further saturable absorber crystal, to ensure that just one might make far more compact Q-switched laser setups with lower inner parasitic losses. Even so, unwelcome Unwanted effects could also occur, for example acquiring undesired valence states on the concerned ions or Strength transfers.

Laser crystals are optical crystals �?usually solitary crystals (monocrystalline optical supplies) �?that happen to be made use of as acquire media for sound-condition lasers. Typically, they are doped with either trivalent uncommon earth ions or transition metallic ions.
