In this article you'll be able to post questions and opinions. So far as they get acknowledged with the writer, they may show up above this paragraph together with the author’s solution. The creator will determine acceptance depending on specified conditions. Fundamentally, The difficulty need to be of sufficiently wide curiosity.
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。
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。
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 offers all widespread laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etc.) using a broad range of technical specs. Besides the effectively-proven materials, innovative crystals with exceptional Qualities like Yb:CALGO can open new horizons for demanding laser apps. It does not matter whether or not personal pieces for R & D needs are essential or Value-productive figures in little, medium or significant batches with in-time shipping for that creation line are needed: GWU’s committed services really helps to find the most effective core parts to your software.
激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。
The maximum attainable doping focus can count strongly on the host content and its fabrication approach.
Some laser click here crystal elements have been shown where some saturable absorber material is incorporated for passive Q switching of a laser.
激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。
For quasi-three-stage laser acquire media as well as 3-amount obtain media, just one generally really should Restrict the size to a price that's too short for economical pump absorption, as reabsorption consequences would otherwise spoil the efficiency. For side pumping, supplemental concerns come into Participate in; Apart from productive pump absorption, it's important to acquire a suitable spatial form in the get profile.
主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。
The medium should have a significant transparency (small absorption and scattering) within the wavelength locations of pump and laser radiation, and excellent optical homogeneity. To some extent, this depends upon the quality of the material, based on facts on the fabrication approach.
With That idea, a person would not need to have a further saturable absorber crystal, in order that a person may possibly make a lot more compact Q-switched laser setups with decreased inner parasitic losses. However, unwanted Unwanted side effects might also happen, for instance obtaining unwanted valence states on the included ions or Vitality 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。
