Distinct crystalline supplies are very unique concerning their hardness and various Qualities, which ascertain with which procedures And the way conveniently they are often Reduce and polished with top 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 a lot more than simply a method to fix the laser-active ions at specified positions in space. Several Houses of your host material are essential:

This is straightforward to carry out: just locate the lock icon before the URL in the address bar and drag that on the bookmark toolbar Along with the mouse. Just in case you locate the bookmark entry much too long, you'll be able to proper-click on it to edit the text, e.g. making use of "RP Enc" as an alternative to "RP Photonics Encyclopedia".

For quasi-3-degree laser gain media or perhaps a few-stage achieve media, one particular typically has to limit the length to a price which can be too shorter for successful pump absorption, as reabsorption results would or else spoil the performance. For aspect pumping, extra considerations occur into Perform; Moreover economical pump absorption, it is necessary to obtain an appropriate spatial condition of your obtain profile.

(Should you later on retract your consent, we will delete those inputs.) As your inputs are to start with reviewed through the creator, They might be released with some hold off.

GWU-Lasertechnik has in excess of thirty a long time of expertise in distributing laser crystals. Select GWU to reap the benefits of our wide awareness and in-field practical experience!

A superior injury threshold when it comes to pulse fluence or peak intensity is usually essential for high-Strength 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：

These tables consist of only the commonest host crystals; numerous Other folks exist, that are a lot less often applied.

The most common laser-Energetic exceptional earth ions and host media together with some standard emission wavelengths are revealed in the subsequent table:

Several laser crystal components happen to be shown wherever some saturable absorber content is incorporated for passive Q switching of the laser.

Obviously, it is vitally appealing that a given crystal excellent is created continuously, Though distinctive laser types might have a special sensitivity to substance parameters.

There's a wide array of crystalline media, that may be grouped in accordance to important atomic constituents and crystalline constructions. Some significant teams of crystals are:

With That idea, just one doesn't need to have a further saturable absorber crystal, so that 1 may possibly make additional compact Q-switched here laser setups with lower internal parasitic losses. Nonetheless, undesirable Unintended effects may also occur, like obtaining unwelcome valence states on the associated ions or energy transfers.

It is clear that different applications bring about incredibly distinctive requirements on laser obtain media. For that reason, a wide array of various crystals are made use of, and earning the right option is essential for constructing lasers with optimum overall performance.

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。
