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 straightforward to do: just locate the lock icon before the URL within the handle bar and drag that for the bookmark toolbar Together with the mouse. In the event you locate the bookmark entry too very long, you could ideal-click it to edit the text, e.g. working with "RP Enc" in place of "RP Photonics Encyclopedia".
GWU gives all popular laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so on.) having a broad number of technical specs. In addition to the effectively-established resources, revolutionary crystals with fantastic Attributes like Yb:CALGO can open new horizons for demanding laser programs. Regardless of whether or not particular person parts for R & D reasons are needed or Expense-effective quantities in compact, medium or huge batches with in-time shipping and delivery to the generation line are required: GWU’s committed assistance really helps to discover the most effective Main elements for the software.
A substantial area excellent is not surprisingly significant. Specifications of area flatness are frequently a lot better than . This helps to stop both of those scattering losses and wavefront distortions which might degrade the laser's beam good quality. Moreover, scratch and dig requirements
亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力,这对激光动作至关重要。
The host crystal is a great deal more than just a means to fix the laser-Lively ions at sure positions in space. A number of properties of the host product are crucial:
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
These surfaces which happen to be handed via the laser beam are Commonly both oriented at Brewster's angle or have an anti-reflection coating.

The medium ought to have a superior transparency (lower absorption and scattering) website within the wavelength areas of pump and laser radiation, and great optical homogeneity. To some extent, this relies on the caliber of the fabric, based on facts of the fabrication method.
Employing our advertising deal, you are able to Display screen your logo, even further down below your merchandise description, and these will been witnessed by a lot of photonics specialists.
