Ho: YAG Makristasi
Ho:YAG Ho3+maion akadonhedzwa mune inodzivirira laser makristasi akaratidzira gumi nemana inter-manifold laser chiteshi, anoshanda mumodhi yenguva kubva kuCW kuenda kumodhi-yakakiiwa.Ho: YAG inowanzoshandiswa senzira inoshanda yekugadzira 2.1-μm laser emission kubva ku5I7-5I8shanduko, yezvishandiso zvakaita senge laser kure sensing, kuvhiyiwa kwekurapa, uye kupomba Mid-IR OPO's kuwana 3-5micron emission.Yakananga diode pumped masisitimu, uye Tm: Fiber Laser pumped system yakaratidza hi slope efficiencies, vamwe vachiswedera kumuganhu we theoretical.
