Right here you are able to post issues and comments. As far as they get acknowledged with the writer, they will seem previously mentioned this paragraph together with the writer’s reply. The writer will make a decision on acceptance based upon selected standards. Primarily, The problem has to be of sufficiently broad desire.

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。

This is a snap to perform: just locate the lock icon in front of the URL while in the handle bar and drag that for the bookmark toolbar While using the mouse. In case you discover the bookmark entry far too long, you'll be able to suitable-simply click it to edit the textual content, e.g. utilizing "RP Enc" in lieu of "RP Photonics Encyclopedia".

GWU presents all popular laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) with a wide a number of technical specs. Other than the perfectly-founded elements, impressive crystals with remarkable Homes like Yb:CALGO can open new horizons for demanding laser purposes. Regardless of whether or not individual pieces for R & D applications are essential or Price-successful figures in smaller, medium or huge batches with in-time supply to the output line are necessary: GWU’s devoted company helps to discover the greatest core parts for your application.

A substantial area high quality is naturally vital. Specifications of surface flatness are frequently a lot better than . This will help to prevent equally scattering losses and wavefront distortions which often can degrade the laser's beam excellent. Moreover, scratch and dig requirements

g. a thin disk. As One more case in point, Q-switched lasers achieve the next population density while in the higher laser amount and are for that reason extra sensitive to quenching effects and Vitality transfer procedures; thus, a decreased doping density is often appropriate for these gadgets. For high-electrical power lasers, decrease doping densities in many cases are utilized to Restrict the density of heat era, Though skinny-disk lasers perform greatest with very doped crystals. Numerous laser products and solutions never get to the comprehensive Laser Crystal overall performance potential for the reason that these information have not been adequately worked out.

激光晶体的效率在很大程度上依赖于某些属性，这些属性不仅限于其基本组成。这些特性决定了产生的激光光束的质量和随后的应用。

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-a few-stage laser obtain media or even 3-stage attain media, 1 normally should Restrict the length to a price that is far too small for efficient pump absorption, as reabsorption consequences would in any other case spoil the overall performance. For side pumping, extra criteria appear into play; besides effective pump absorption, it's important to acquire an acceptable spatial shape in the attain profile.

The medium should have a superior transparency (very low absorption and scattering) inside the wavelength locations of pump and laser radiation, and very good optical homogeneity. To some extent, this is determined by the standard of the material, based on particulars of the fabrication process.
