These tables incorporate only the most typical host crystals; quite a few Many others exist, which can be a lot less frequently utilized.

Listed here you'll be able to submit thoughts and opinions. As far as they get recognized via the author, they're going to look higher than this paragraph along with the creator’s reply. The writer will determine acceptance based on specific standards. Basically, The difficulty has to be of sufficiently broad fascination.

为了使激光器有效运作，需要有效管理运行过程中产生的热量。具有良好热导率的激光晶体可以更有效地散热，防止热透镜效应或断裂。

The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions and in addition the higher-state lifetime.

A high area good quality is naturally important. Requirements of surface flatness in many cases are a lot better than . This can help in order to avoid both of those scattering losses and wavefront distortions which might degrade the laser's beam high-quality. Moreover, scratch and dig specifications

The most possible doping focus can rely strongly around the host content and its fabrication technique.

The host crystal is way more than just a method to fix the laser-Lively ions at specified positions in Area. Many Homes of the host substance are important:

热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。

It is clear that unique apps cause quite distinct needs on laser obtain media. Because of this, a wide vary of various crystals are applied, and generating the correct option is important for developing lasers with ideal overall performance.

The medium must have a significant transparency (small absorption and scattering) in the wavelength locations of pump and laser radiation, and good optical homogeneity. To some extent, this will depend on the standard of the fabric, based on information on the fabrication approach.

With That idea, 1 would not have to have a further saturable absorber crystal, in order that a person may possibly make much more compact Q-switched laser setups with decreased internal parasitic losses. On the other hand, unwanted side effects may additionally occur, for example getting unwanted valence states with the get more info involved ions or Vitality transfers.

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。
