Unique crystalline supplies are extremely unique concerning their hardness and various Homes, which identify with which strategies And just how easily they are often Slice 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 just a means to fix the laser-active ions at specific positions in Room. A variety of Attributes of the host materials are essential:
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。
The utmost probable doping concentration can count strongly within the host product and its fabrication approach.

In addition, some adaptability is dropped in experiments if 1 simply cannot try out absorbers with different thickness or doping focus, for instance, without the need of exchanging the laser crystal by itself.
These ions permit the crystal to amplify light on the laser wavelength by means of stimulated emission, when Power is provided to the crystal through absorption of pump light-weight (�?optical pumping

These tables consist of only the commonest host crystals; quite a few Other folks click here exist, which might be considerably less usually utilised.
Below it is possible to submit questions and opinions. In terms of they get acknowledged from the creator, they may look over this paragraph along with the writer’s solution. The creator will make a decision on acceptance depending on certain conditions. Primarily, the issue need to be of sufficiently wide interest.
Those people surfaces that happen to be passed with the laser beam are Usually possibly oriented at Brewster's angle or have an anti-reflection coating.
Of course, it is rather attractive that a given crystal good quality is manufactured regularly, Despite the fact that distinctive laser designs can have a distinct sensitivity to substance parameters.
There is a wide range of crystalline media, which can be grouped in accordance to special atomic constituents and crystalline buildings. Some vital teams of crystals are:

It is obvious that diverse programs bring about extremely diverse prerequisites on laser gain media. Because of this, a wide array of various crystals are used, and creating the correct decision is important for developing lasers with the best possible 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。
