Rapid Delivery for Optical Interference Filter - Ho: YAG Crystals – Dien Detail:

Ho:YAG Ho3+ ions doped into insulating laser crystals have exhibited 14 inter-manifold laser channels, operating in temporal modes from CW to mode-locked . Ho:YAG is commonly used as an efficient means to generate 2.1-μm laser emission from the 5I7- 5I8 transition, for applications such as laser remote sensing, medical surgery, and pumping Mid-IR OPO’s to achieve 3-5micron emission. Direct diode pumped systems,and Tm: Fiber Laser pumped system have demonstrated hi slope efficiencies, some approaching the theoretical limit.
