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 not difficult to try and do: just locate the lock icon before the URL inside the handle bar and drag that on the bookmark toolbar Along with the mouse. In case you locate the bookmark entry way too prolonged, you can ideal-click it to edit the textual content, e.g. making use of "RP Enc" as an alternative to "RP Photonics Encyclopedia".
GWU delivers all prevalent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) with a wide variety of specifications. Apart from the effectively-proven components, progressive crystals with excellent properties like Yb:CALGO can open up new horizons for demanding laser apps. Irrespective of regardless of whether personal parts for R & D needs are needed or Charge-productive numbers in smaller, medium or big batches with in-time shipping and delivery with the creation line are desired: GWU’s devoted company helps to click here discover the best core parts for your personal application.
Not surprisingly, it's very fascinating that a presented crystal good quality is made constantly, Though various laser designs might have a distinct sensitivity to materials parameters.
The most achievable doping focus can rely strongly over the host content and its fabrication method.
The host crystal is considerably more than simply a method to fix the laser-Energetic ions at selected positions in space. Several Houses of your host materials are very important:
热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。
People surfaces which can be handed because of the laser beam are Ordinarily both oriented at Brewster's angle or have an anti-reflection coating.

The medium must have a large transparency (low absorption and scattering) during the wavelength areas of pump and laser radiation, and good optical homogeneity. To some extent, this relies on the caliber of the fabric, determined by facts in the fabrication process.
With that concept, a single will not want an extra saturable absorber crystal, in order that just one may well make far more compact Q-switched laser setups with reduced internal parasitic losses. However, unwelcome Unintended effects may take place, like getting unwanted valence states of your concerned ions or Electrical power transfers.
