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。
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions as well as the higher-point out life time.
GWU gives all widespread laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) with a wide number of specs. Apart from the effectively-set up supplies, innovative crystals with superb Houses like Yb:CALGO can open new horizons for demanding laser applications. It doesn't matter irrespective of whether particular person pieces for R & D purposes are expected or Expense-efficient numbers in smaller, medium or huge batches with in-time supply for your output line are necessary: GWU’s focused services helps you to locate the very best Main factors for your application.
A significant area top quality is naturally important. Specs of surface area flatness in many cases are much better than . This allows to avoid each scattering losses and wavefront distortions which might degrade the laser's beam here good quality. Moreover, scratch and dig requirements
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 employed to reliably establish the ideal crystal dimensions, doping density And maybe values of extra parameters.
量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。
It is apparent that distinct apps cause incredibly distinctive prerequisites on laser gain media. For this reason, a wide vary of various crystals are employed, and producing the correct selection is essential for constructing lasers with the best possible effectiveness.

In 2017, we produced the world’s premier Ti∶sapphire crystal (Φ235 mm), which supported The ten PW laser output of Shanghai Superintense Ultrafast Laser Facility. The event of Yb and Tm doped GdScO3 laser crystals with incredibly huge emission spectra drives the development of laser diode pumped ultrafast sound-condition lasers. With the rise in pulse energy, peak electrical power, and repetition amount of solid-condition lasers, laser crystals will create in the direction of larger dimensions, increased crystal high quality, and controllable vital effectiveness.
It might be oriented for in close proximity to perpendicular incidence of your laser beam, or at Brewster's angle. It might be fixed in certain solid mount which also functions to be a warmth sink. Much larger crystals usually are useful for aspect pumping e.g. with substantial-electricity diode bars.
