Below you are able to submit thoughts and feedback. So far as they get recognized by the creator, they will seem higher than this paragraph together with the author’s response. The writer will make a decision on acceptance based on sure criteria. Basically, The difficulty need to be of adequately wide 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。
激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。
The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions as well as the upper-state lifetime.
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。
A superior surface area good quality is needless to say important. Specs of surface area flatness will often be much better than . This can help to avoid both of those scattering losses and wavefront distortions which may degrade the laser's beam high-quality. Furthermore, scratch and dig technical specs
亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。
A few laser crystal resources are actually shown exactly where some saturable absorber substance is included for passive Q switching of the laser.
量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。
For quasi-3-degree laser attain media as well as a few-level achieve media, a person frequently has to limit the length to a worth which happens to be as well short for economical pump absorption, as reabsorption consequences would usually spoil the effectiveness. For facet pumping, supplemental things to consider appear into Engage in; Aside from successful pump absorption, it is crucial to acquire a suitable spatial shape in the acquire profile.

The medium ought to have a high transparency (lower absorption and scattering) within the wavelength regions of pump and laser radiation, and good optical homogeneity. To some extent, this is dependent upon the standard of the fabric, determined by particulars with the fabrication method.
With that concept, 1 will get more info not have to have an additional saturable absorber crystal, so that one particular may well make extra compact Q-switched laser setups with decrease inner parasitic losses. However, unwanted side effects can also happen, including getting unwanted valence states of the included ions or Electricity 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。
