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。
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 and in addition the upper-condition life time.
GWU presents all widespread laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so forth.) that has a wide a number of specifications. Aside from the effectively-founded components, innovative crystals with remarkable Houses like Yb:CALGO can open up new horizons for demanding laser apps. It does not matter no matter whether specific items for R & D applications are needed or Expense-efficient quantities in little, medium or large batches with in-time shipping and delivery for that manufacturing line are desired: GWU’s dedicated service helps to discover the very best Main elements for the software.
Needless to say, it is rather appealing that a offered crystal high-quality is generated regularly, Despite the fact that different laser designs can have a special sensitivity to materials parameters.
The maximum attainable doping concentration can depend strongly to the host materials and its fabrication method.
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。
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-3-level laser gain media or simply 3-amount achieve media, a single often ought to limit the size to a value and that is also short for efficient pump absorption, as reabsorption outcomes would or else spoil the performance. For side pumping, more concerns appear into Participate in; Apart from successful pump absorption, it's important to get an appropriate spatial read more form of your acquire profile.

The medium must have a higher transparency (lower absorption and scattering) during the wavelength areas of pump and laser radiation, and great optical homogeneity. To some extent, this is dependent upon the standard of the material, determined by aspects on the fabrication process.
With that concept, one does not need yet another saturable absorber crystal, to make sure that 1 may make much more compact Q-switched laser setups with lower inner parasitic losses. Nonetheless, unwanted Negative effects might also occur, for instance acquiring unwelcome valence states on the involved ions or Electrical power transfers.
