Diverse crystalline elements are very unique concerning their hardness and other Attributes, which establish with which approaches And just how effortlessly they can be Slash and polished with top quality.
The medium ought to have a high transparency (minimal absorption and scattering) while in the wavelength areas of pump and laser radiation, and good optical homogeneity. To some extent, this depends upon the quality of the material, determined by aspects in the fabrication process.
The host crystal is a great deal more than just a method to repair the laser-Energetic ions at particular positions in House. Several Houses of your host content are crucial:
激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。
The utmost attainable doping concentration can rely strongly within the host material and its fabrication system.
g. a thin disk. As One more case in point, Q-switched lasers get to a higher populace density inside the higher laser amount and are thus much more sensitive to quenching effects and Electrical power transfer processes; therefore, a decreased doping density is commonly suitable for these equipment. For top-electrical power lasers, decrease doping densities are frequently accustomed to Restrict the density of warmth era, although thin-disk lasers function ideal with hugely doped crystals. A lot of laser solutions tend not to reach the comprehensive functionality possible mainly because such particulars have not been properly worked out.
GWU-Lasertechnik has in excess of thirty yrs of knowledge in distributing laser crystals. Choose GWU to take advantage of our wide awareness and in-subject expertise!
A large problems threshold in terms of pulse fluence or peak intensity can be essential for top-Vitality amplifiers.
作为工业上使用较多的都是高掺钇铝石榴石，也就是说掺入不同的元素来达到不同的效果；作为工业激光，关注以下性能：

These tables incorporate only the most typical host crystals; numerous Other people exist, which might be a lot less usually used.
The most typical laser-Lively uncommon earth ions and host media along with some common emission wavelengths are demonstrated in the subsequent table:
A handful of laser crystal products happen to be demonstrated in which some saturable absorber materials is included for passive Q switching of a laser.
Of course, it is vitally desirable that a supplied crystal excellent is created regularly, Though unique laser styles might have a distinct sensitivity to materials parameters.
There's a wide range of crystalline media, that may be grouped according to important atomic constituents and crystalline constructions. Some vital groups of crystals are:
With that concept, a person does not need yet another saturable absorber crystal, making sure that 1 may possibly make extra compact Q-switched laser setups with reduce inside parasitic losses. Even so, undesirable Unwanted side effects could also read more come about, such as acquiring undesirable valence states on the associated ions or Strength transfers.
GWU presents all frequent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etc.) using a wide variety of specifications. In addition to the effectively-proven supplies, impressive crystals with superb properties like Yb:CALGO can open new horizons for demanding laser programs. Irrespective of no matter if particular person items for R & D functions are essential or Expense-productive figures in smaller, medium or large batches with in-time delivery to the creation line are necessary: GWU’s dedicated company helps you to find the ideal Main factors for your personal software.
It is apparent that unique programs produce quite various needs on laser gain media. Due to this, a broad selection of various crystals are utilized, and generating the ideal option is important for constructing lasers with optimum effectiveness.
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。
