These tables comprise only the most common host crystals; lots of Other people exist, which are considerably less commonly used.
Listed here it is possible to submit thoughts and reviews. As far as they get approved by the writer, they can show up above this paragraph along with the creator’s response. The author will make a decision on acceptance depending on specific requirements. Primarily, The difficulty needs to be of adequately wide interest.
Laser crystals are optical crystals �?commonly solitary crystals (monocrystalline optical products) �?which are used as acquire media for stable-state lasers. Generally, These are doped with possibly trivalent scarce earth ions or changeover metallic ions.
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。
This is simple to accomplish: just find the lock icon in front of the URL inside the tackle bar and drag that to the bookmark toolbar Using the mouse. Just in case you locate the bookmark entry too long, you'll be able to correct-simply click it to edit the text, e.g. employing "RP Enc" in place of "RP Photonics Encyclopedia".
GWU features all frequent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so forth.) that has a broad number of requirements. In addition to the well-established products, impressive crystals with outstanding properties like Yb:CALGO can open up new horizons for demanding laser apps. It does not matter irrespective of whether particular person items for R & D reasons are needed or Price tag-efficient numbers in modest, medium or large batches with in-time shipping and delivery for your production line are essential: GWU’s committed services helps to locate the greatest Main parts to your software.
活性离子在激光晶体内发生的能量跃迁对激光操作至关重要。大多数激光操作都是通过四能级系统原理进行的，确保连续操作并防止浪费的非辐射衰变。
The maximum achievable doping focus can depend strongly within the host content and its fabrication system.
Laser modeling and simulation can be employed to reliably establish the optimum crystal Proportions, doping density And perhaps values of extra parameters.
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-a few-level laser obtain media or maybe a few-amount acquire media, one frequently needs to Restrict the duration to a value which is much too short for efficient pump absorption, as reabsorption outcomes would otherwise spoil the efficiency. For facet pumping, additional concerns appear into Perform; Apart from economical pump absorption, it's important to get a suitable spatial condition on the obtain profile.

The medium must have a high transparency (low absorption and scattering) in the wavelength regions of pump read more and laser radiation, and fantastic optical homogeneity. To some extent, this relies on the quality of the material, based on particulars of your fabrication method.
With That idea, just one isn't going to need a further saturable absorber crystal, to ensure 1 may well make extra compact Q-switched laser setups with decreased inner parasitic losses. However, undesirable side effects may additionally manifest, like obtaining undesirable valence states on the included ions or Electrical power transfers.
