晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。

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。

g. a skinny disk. As A further illustration, Q-switched lasers arrive at an increased inhabitants density from the upper laser degree and are hence extra sensitive to quenching outcomes and Strength transfer processes; consequently, a reduce doping density is often suitable for these units. For prime-power lasers, lower doping densities in many cases are accustomed to Restrict the density of heat technology, While thin-disk lasers work ideal with extremely doped crystals. Many laser goods never get to the entire performance probable simply because these particulars have not been effectively worked out.

The host crystal is a lot more than just a means to repair the laser-Lively ions at selected positions in House. Many Houses on the host content are essential:

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。

Those people surfaces which can be handed from the laser beam are Typically possibly oriented at Brewster's angle or have an anti-reflection coating.

主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。

In 2017, we produced the entire world’s most significant 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 particularly vast emission spectra drives the development of laser diode pumped ultrafast reliable-condition lasers. With the rise in pulse Strength, peak power, and repetition rate of good-point out lasers, laser crystals will acquire to bigger sizes, better crystal high-quality, and controllable vital general performance.

It could be oriented for close to perpendicular incidence in the laser beam, or at Brewster's angle. It may be set in certain strong mount which also functions being a warmth sink. Bigger crystals are usually used for facet pumping e.g. with substantial-energy more info diode bars.
