These tables have only the most common host crystals; numerous Other folks exist, which might be fewer usually utilised.
Right here it is possible to submit questions and reviews. So far as they get recognized from the writer, they can look over this paragraph together with the writer’s solution. The author will make a decision on acceptance based upon specific requirements. Primarily, the issue need to be of adequately 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。
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 changeover cross-sections of pump and laser transitions in addition to the upper-point out lifetime.
GWU gives all typical laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so forth.) having a wide a number of specs. Aside from the perfectly-founded elements, progressive crystals with superb Houses like Yb:CALGO can open new horizons for demanding laser programs. Irrespective of irrespective of whether personal pieces for R & D uses are required or Price-productive numbers in smaller, medium or large batches with in-time shipping and delivery for that production line are required: GWU’s devoted assistance really helps to find the best core components to your software.
Obviously, it is very fascinating that a provided crystal excellent is made persistently, although distinctive laser patterns might have another sensitivity to product parameters.
g. a skinny disk. As An additional instance, Q-switched lasers access a greater populace density while in the upper laser amount and they are consequently more delicate to quenching outcomes and Electricity transfer procedures; hence, a decreased doping density is often appropriate for these devices. For high-power lasers, lower doping densities are frequently accustomed to Restrict the density of heat era, Whilst slender-disk lasers function greatest with highly doped crystals. Numerous laser products and solutions never reach the entire effectiveness prospective for the reason that these types of information have not been adequately worked out.
Laser modeling and simulation may be used to reliably ascertain the the best possible crystal Proportions, doping density And perhaps values Laser Crystal of more parameters.
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。

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 must have a superior transparency (reduced absorption and scattering) while in the wavelength areas of pump and laser radiation, and excellent optical homogeneity. To some extent, this is dependent upon the caliber of the fabric, determined by specifics from the fabrication method.
Using our advertising package, you are able to display your logo, additional below your product or service description, and these will been witnessed by a lot of photonics professionals.
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。
