These tables comprise only the most common host crystals; a lot of others exist, that happen to be less regularly applied.

Laser crystals are optical crystals �?usually solitary crystals (monocrystalline optical materials) �?that happen to be made use of as attain media for stable-state lasers. Typically, They are really doped with possibly trivalent rare earth ions or transition metallic ions.

Which geometry, dopant and doping focus in the gain medium are most beneficial count on several aspects. The out there pump source (style of laser diode or lamp) and also the envisaged pumping arrangement are crucial aspects, but the fabric alone also has some impact. For example, titanium–sapphire lasers must be pumped with significant intensities, for which the form of the transversely cooled rod, operated with relatively small pump and laser beam diameter, is much more suitable than e.
激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。
Obviously, it is vitally appealing that a supplied crystal high quality is generated regularly, While different laser types get more info might have a different sensitivity to content parameters.
The maximum attainable doping focus can count strongly within the host content and its fabrication process.
A handful of laser crystal resources have already been demonstrated wherever some saturable absorber content is incorporated for passive Q switching of the laser.

GWU-Lasertechnik has more than 30 several years of experience in distributing laser crystals. Pick GWU to take pleasure in our broad expertise As well as in-industry encounter!
With That idea, one particular doesn't have to have a further saturable absorber crystal, to ensure that a person could make more compact Q-switched laser setups with decrease internal parasitic losses. On the other hand, unwanted side effects may additionally occur, for example getting undesirable valence states with the involved ions or Strength transfers.
