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 a snap to carry out: just locate the lock icon before the URL in the tackle bar and drag that into the bookmark toolbar With all the mouse. Just in case you locate the bookmark entry as well prolonged, you could correct-click it to edit the text, e.g. making use of "RP Enc" in place of "RP Photonics Encyclopedia".
GWU delivers all prevalent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and many others.) which has a wide range of technical specs. Apart from the effectively-proven supplies, modern crystals with exceptional Qualities like Yb:CALGO can open up new horizons for demanding laser apps. Irrespective of regardless of whether person parts for R & D reasons are required or cost-successful numbers in compact, medium or massive batches with in-time supply for the creation line are essential: GWU’s dedicated company helps to discover the finest Main components on your software.
激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。
探索激光晶体的领域，可以让我们看到科学和技术相结合的奇迹，为我们带来了令人难以置信的进步。这些激光晶体，每一种都在组成和特性上独具匠心，是推动现代世界众多应用的动力。
Laser modeling and simulation can be utilized to reliably check here identify the optimum crystal dimensions, doping density And perhaps values of supplemental parameters.
激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。
For quasi-3-level laser attain media or even 3-level get media, a single normally should Restrict the length to a price that is far too brief for successful pump absorption, as reabsorption effects would normally spoil the performance. For side pumping, added criteria come into Engage in; besides effective pump absorption, it is necessary to get an appropriate spatial condition of your gain profile.

In 2017, we developed the earth’s biggest Ti∶sapphire crystal (Φ235 mm), which supported the 10 PW laser output of Shanghai Superintense Ultrafast Laser Facility. The event of Yb and Tm doped GdScO3 laser crystals with extremely vast emission spectra drives the event of laser diode pumped ultrafast good-state lasers. With the increase in pulse Power, peak electrical power, and repetition level of solid-state lasers, laser crystals will build in direction of much larger dimensions, larger crystal good quality, and controllable essential effectiveness.
It may be oriented for close to perpendicular incidence in the laser beam, or at Brewster's angle. It may be mounted in a few sound mount which also acts as being a heat sink. Larger crystals are usually useful for aspect pumping e.g. with substantial-electrical power diode bars.
