The most common laser-active rare earth ions and host media along with some regular emission wavelengths are demonstrated in the next table:
Listed here you'll be able to submit inquiries and remarks. In terms of they get accepted via the author, they may look higher than this paragraph along with the author’s response. The writer will make a decision on acceptance according to specific requirements. Primarily, The difficulty has to be of adequately broad fascination.
激光晶体是固态激光器的核心。它们是光放大发生的媒介，产生激光束。在这篇全面指南中，我们深入探讨激光晶体的世界。

The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions as well as the higher-condition lifetime.
GWU features all prevalent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so forth.) using a broad a number of specifications. Aside from the very well-founded products, revolutionary crystals with remarkable Homes like Yb:CALGO can open new horizons for demanding laser apps. It does not matter no matter whether individual parts for R & D applications are essential or cost-successful quantities in small, medium or massive batches with in-time shipping for the creation line are wanted: GWU’s committed support helps you to discover the greatest core components for 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。
g. a thin disk. As another case in point, Q-switched lasers access an increased inhabitants density during the higher laser stage and therefore are for that reason far more delicate to quenching effects and Electricity transfer processes; as a result, a reduced doping density is frequently appropriate for these equipment. For high-electrical power lasers, reduce doping densities are sometimes utilized to Restrict the density of heat era, Even though slender-disk lasers perform most effective with very doped crystals. Lots of laser merchandise never reach the total general performance possible due to the fact these kinds of particulars haven't been thoroughly labored 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。

It is clear that distinctive purposes bring about pretty distinctive needs on laser attain media. Because of this, a broad vary of different crystals are employed, and building the correct preference is important for constructing lasers with the best possible overall performance.

The medium ought to have a significant transparency (reduced absorption here and scattering) from the wavelength locations of pump and laser radiation, and fantastic optical homogeneity. To some extent, this is determined by the caliber of the material, based on particulars with the fabrication course of action.
It may be oriented for in the vicinity of perpendicular incidence with the laser beam, or at Brewster's angle. It can be fastened in a few reliable mount which also acts as a warmth sink. Greater crystals are usually employed for aspect pumping e.g. with higher-power diode bars.
