YLF/Tm:YLF/YLF bonding crystals with the size of 5 mm(height)×20 mm(width)×40 mm(length) were prepared by a thermal diffusion method. The middle of the bonding crystal is Tm:YLF with the length of 35 mm and the doping amount of Tm ions of 2.0% mole fraction. The both ends of the bonding crystal are YLF crystals. The effect of heat treatment on the quality of bonding crystal was investigated. The result shows that it is possible to obtain a good quality bonding crystal at a pressure of 0.4 MPa and the heat t...

键合技术是指在不需要任何粘合剂的条件下,把两块经过抛光处理的晶片进行表面清洁、活化处理,然后将表面光滑、平整、清洁的晶片对放在一起,通过Van der Waals力或以其它成键方式粘合在一起实现预键合,在空气或真空环境中通过一定温度热处理从而形成一块整体晶体的技术[1]。通?
