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。
This is a snap to perform: just locate the lock icon in front of the URL during the deal with bar and drag that to your bookmark toolbar with the mouse. In case you find the bookmark entry also prolonged, you can proper-click on it to edit the textual content, e.g. working with "RP Enc" instead of "RP Photonics Encyclopedia".
GWU features all typical laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so on.) using a broad range of technical specs. Moreover the properly-set up components, modern crystals with fantastic Qualities like Yb:CALGO can open new horizons for demanding laser applications. Despite no matter if specific pieces for R & D uses are necessary or cost-successful numbers in modest, medium or large batches with in-time supply to the manufacturing line are needed: GWU’s dedicated support really helps to find the finest Main components in your application.
A substantial surface good quality is of course critical. Technical specs of floor flatness are frequently better than . This helps to prevent the two scattering losses and wavefront distortions which often can degrade the laser's beam excellent. Also, scratch and dig requirements
The utmost possible doping focus can rely strongly around the host product and its fabrication approach.
Laser modeling and simulation can be used to reliably identify the ideal crystal Proportions, doping density And perhaps values of extra parameters.

The medium must have a high 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, determined by details with the fabrication procedure.
With that concept, a single isn't going to need to have a further saturable absorber crystal, to make sure that get more info a person may perhaps make extra compact Q-switched laser setups with lower interior parasitic losses. Having said that, unwanted Unintended effects can also arise, for instance acquiring unwelcome valence states in the associated ions or Vitality transfers.
