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 and likewise the higher-state life span.

A significant area quality is obviously important. Specifications of surface flatness tend to be better than . This helps to avoid both of those scattering losses and wavefront distortions that may degrade the laser's beam high-quality. Also, scratch and dig requirements
g. a skinny disk. As An additional instance, Q-switched lasers attain an increased inhabitants density in the upper laser level and therefore are hence more sensitive to quenching effects and energy transfer processes; therefore, a lower doping density is often suitable for these equipment. For top-electric power lasers, decrease doping densities in many cases are accustomed to limit the density of heat technology, While skinny-disk lasers operate ideal with very doped crystals. Many laser products don't get to the total overall performance opportunity mainly because this sort of aspects have not been adequately worked out.
The host crystal is a great deal more than simply a method to repair the laser-Lively ions at certain positions in Area. Quite a few Houses with the host product are crucial:
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。
It is clear that unique apps cause quite diverse demands on laser obtain media. For that reason, a broad range of various crystals are utilised, and generating the best selection is essential for setting up lasers with optimum general performance.

The medium should have a substantial transparency (reduced absorption and scattering) during the wavelength regions of pump and laser radiation, and superior optical homogeneity. To some extent, this is dependent upon the quality of the material, based on particulars with the fabrication procedure.
With That idea, a person would not will need a further saturable absorber crystal, to ensure a person may perhaps make additional compact Q-switched laser setups check here with reduced internal parasitic losses. Nevertheless, unwanted side effects may take place, including getting undesirable valence states with the involved ions or Electricity transfers.
