Here it is possible to post issues and opinions. In terms of they get recognized by the author, they will appear over this paragraph together with the author’s answer. The creator will make a decision on acceptance dependant on selected standards. In essence, The problem should be of adequately broad interest.
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。
Moreover, some overall flexibility is shed in experiments if a single are not able to Check out absorbers with unique thickness or doping focus, for example, with out exchanging the laser crystal itself.
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：
GWU gives all widespread laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so forth.) using a broad a number of requirements. Aside from the effectively-established elements, modern crystals with exceptional Attributes like Yb:CALGO can open new horizons for demanding laser purposes. No matter whether particular person parts for R & D reasons are demanded or Expense-economical numbers in modest, medium or significant batches with in-time shipping and delivery for that output line are necessary: GWU’s committed company really helps to find the very best Main factors for your personal application.
A higher surface area good quality is not surprisingly vital. Technical specs of surface area flatness are sometimes a lot better than . This aids in order to avoid the two scattering losses and wavefront distortions which might degrade the laser's beam top quality. Additionally, scratch and dig specifications
The maximum doable doping focus can depend strongly to the host material and its fabrication approach.
The host crystal is far more than just a way to fix the laser-Energetic ions at specified positions in House. Quite a few Houses of your host material are important:

It is clear that unique apps bring on quite diverse demands on laser obtain media. Because of this, a wide range of various crystals are made use of, and building the best selection is essential for setting up lasers with optimum general performance.

The medium ought to have a large transparency (low absorption and scattering) from the wavelength regions of pump and laser radiation, and fantastic optical homogeneity. To some extent, this is determined by the standard of the material, determined by facts from the fabrication course of action.
With That idea, one particular isn't going to need to have an additional saturable absorber crystal, to make sure that a person may well make far more compact Q-switched more info laser setups with reduced internal parasitic losses. Having said that, undesirable Negative effects could also come about, including getting undesirable valence states of your concerned ions or Electrical power transfers.
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。
