Laser modeling and simulation can be employed to reliably figure out the optimum crystal Proportions, doping density and possibly values of additional parameters.
人造红宝石激光晶体是首次实现激光输出的材料。可用焰熔法、提拉法或助熔剂法生产单晶。用提拉法容易获得大尺寸优质晶体。
The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions as well as the upper-point out life span.
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 maximum probable doping focus can count strongly around the host product and its fabrication system.

GWU-Lasertechnik has in excess of thirty a long time of experience in distributing laser crystals. Pick out GWU to benefit from our extensive knowledge and in-industry knowledge!
Additionally, some flexibility is missing in experiments if 1 are not able to Check out absorbers with different thickness or doping concentration, for instance, without exchanging the laser crystal by itself.
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：
Which geometry, dopant and doping concentration with the gain medium are most advantageous depend upon various aspects. The out there pump source (variety of laser diode or lamp) as well as envisaged pumping arrangement are important aspects, but the material by itself also has some affect. By way of example, titanium–sapphire lasers must be pumped with large intensities, for which the form of a transversely cooled rod, operated with comparatively tiny pump and laser beam diameter, is more appropriate than e.
These tables consist of only the commonest host crystals; lots of Many others exist, which might be less regularly employed.
The most common laser-active exceptional earth ions and host media together with some typical emission wavelengths are demonstrated in the next desk:
Some laser crystal products are already demonstrated wherever some saturable absorber product is included for passive Q switching of a laser.
Obviously, it's very desirable that a provided crystal high quality is made continually, although distinct laser styles may have a distinct sensitivity to product parameters.
There exists a wide array of crystalline media, that may be grouped in accordance to important atomic constituents and crystalline structures. Some vital groups of crystals are:
蓝宝�?柱面�?球罩 偏振�?棱镜 红外光学元件 反射�?光学窗口 非球面镜 波片 分光�?制造能力
GWU presents all popular laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and many others.) that has a wide assortment of requirements. Aside from the effectively-proven products, ground breaking crystals with fantastic Qualities like Yb:CALGO can open new horizons for demanding laser applications. Regardless of no matter whether personal items for R & D uses are required click here or Expense-economical quantities in little, medium or large batches with in-time shipping for your production line are desired: GWU’s devoted service helps to find the very best core parts to your application.
It is clear that various purposes bring about pretty distinct requirements on laser obtain media. This is why, a broad selection of various crystals are applied, and earning the right option is essential for constructing lasers with optimum overall performance.
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。
