The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions as well as the higher-condition life span.
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 reach a better population density within the higher laser degree and are hence far more delicate to quenching results and energy transfer processes; therefore, a decreased doping density is commonly appropriate for these equipment. For top-power lasers, decreased doping densities are frequently used to Restrict the density of warmth technology, Even though slender-disk lasers work most effective with remarkably doped crystals. Several laser products do not get to the whole effectiveness potential because this sort of aspects have not been thoroughly labored out.
The host crystal is far more than simply a way to fix the laser-active ions at certain positions in Room. Several Qualities of your host content are important:
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
For quasi-three-level laser acquire media or maybe 3-level achieve media, just one usually really should Restrict the duration to a worth that's also limited for economical pump absorption, as reabsorption outcomes would usually spoil the efficiency. For facet pumping, further things to consider arrive into Participate in; In addition to productive pump absorption, it is important to get an appropriate spatial shape of the achieve profile.
Distinct crystalline components are certainly unique concerning their hardness and also other Attributes, which identify with which procedures And the way easily they can be Reduce and polished with high quality.
