Laser crystals are optical crystals �?ordinarily single crystals (monocrystalline optical components) �?that happen to be utilised as get media for solid-condition lasers. Typically, they are doped with both trivalent unusual earth ions or changeover metal ions.

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 your gain medium are most useful depend on quite a few aspects. The obtainable pump source (type of laser diode or lamp) as well as envisaged pumping arrangement are very important aspects, but the fabric by itself also has some influence. For example, titanium–sapphire lasers should be pumped with high intensities, for which the form of the transversely cooled rod, operated with rather smaller pump and laser beam diameter, is more correct than e.

GWU gives all widespread laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so on.) that has a broad variety of specifications. Apart from the properly-proven resources, impressive crystals with remarkable Homes like Yb:CALGO can open up new horizons for demanding laser programs. It doesn't matter whether or not personal pieces for R & D uses are essential or Expense-effective quantities in tiny, medium or massive batches with in-time delivery for the production line are needed: GWU’s committed services really helps to discover the ideal core factors to your software.

Of course, it is extremely attractive that a offered crystal top quality is created consistently, Whilst diverse laser styles can have a special sensitivity to content parameters.

亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。

The host crystal is way more than just a way to repair the laser-Energetic ions at selected positions in Room. Numerous Attributes with the host substance are essential:

量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。

For quasi-3-stage laser gain media as well as more info 3-amount get media, one generally really should Restrict the size to a worth that is as well limited for efficient pump absorption, as reabsorption consequences would in any other case spoil the functionality. For aspect pumping, more things to consider come into Engage in; besides economical pump absorption, it is necessary to get a suitable spatial form of the obtain profile.

For several good reasons, composite crystals are becoming well known. These have a spatially various chemical composition and might be made with Particular designs.

With that concept, one isn't going to require a further saturable absorber crystal, to ensure that a person may make a lot more compact Q-switched laser setups with lower internal parasitic losses. Even so, unwelcome Unwanted effects may occur, for example getting undesirable valence states from the included ions or Electrical power transfers.
