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 straightforward to do: just discover the lock icon before the URL in the deal with bar and drag that for the bookmark toolbar While using the mouse. In case you discover the bookmark entry far too very long, you can proper-click on it to edit the text, e.g. employing "RP Enc" in lieu of "RP Photonics Encyclopedia".
GWU presents all prevalent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) which has a wide a number of technical specs. Other than the perfectly-founded elements, impressive crystals with superb Houses like Yb:CALGO can open new horizons for demanding laser applications. It doesn't matter whether particular person pieces for R & D applications are necessary or Expense-efficient numbers in smaller, medium or big batches with in-time shipping for your generation line are wanted: GWU’s dedicated service helps you to locate the best core parts for your personal software.
A high surface area quality is needless to say significant. Technical specs of area flatness tend to be better than . This can help to avoid both scattering losses and wavefront distortions which may degrade the laser's beam top quality. Furthermore, scratch and dig specs
g. a thin disk. As A different illustration, Q-switched lasers reach a better inhabitants density while in the higher laser amount and are for that reason extra delicate to quenching effects and Electrical power transfer click here processes; consequently, a decrease doping density is frequently suitable for these products. For prime-electric power lasers, lessen doping densities tend to be used to limit the density of heat generation, although slender-disk lasers do the job finest with remarkably doped crystals. Quite a few laser products and solutions never get to the total efficiency possible because these kinds of particulars haven't been appropriately labored out.
The host crystal is far more than just a means to fix the laser-Energetic ions at selected positions in space. Several Homes with the host product are important:
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。

In 2017, we created the world’s premier Ti∶sapphire crystal (Φ235 mm), which supported The ten PW laser output of Shanghai Superintense Ultrafast Laser Facility. The development of Yb and Tm doped GdScO3 laser crystals with incredibly large emission spectra drives the development of laser diode pumped ultrafast sound-condition lasers. With the rise in pulse Electricity, peak power, and repetition charge of reliable-point out lasers, laser crystals will establish towards bigger sizes, larger crystal good quality, and controllable critical general performance.
With That idea, one doesn't need to have a further saturable absorber crystal, to ensure one particular could make much more compact Q-switched laser setups with lower interior parasitic losses. On the other hand, undesirable Unwanted effects might also manifest, such as acquiring unwanted valence states with the involved ions or Electricity transfers.
