激光技术 激光钕玻璃 包边 残余应力 应力双折射 laser technique Nd:glass edge cladding residual stress stress birefringence
摘要
为减少放大自发辐射和抑制寄生震荡,需在激光钕玻璃片侧面粘接一层吸收介质包边玻璃,其中,包边残余应力是粘接的一个重要参数。详细描述了激光钕玻璃与包边玻璃在包边粘接过程中粘接界面附近残余应力的来源,实验讨论分析了精密退火、加工、包边粘接等对界面附近残余应力的影响。结果表明,退火过程中的边缘应力对粘接界面附近残余应力影响比较大,且包边面加工面型匹配越差,则界面附近残余应力越大,而低收缩率和低模量的粘接胶对界面附近的残余应力影响较小。
Abstract
In order to decrease the reflectivity of amplified spontaneous emission, suppress parasitic oscillations, an edge cladding that absorbs the reflected or scattered light is required. The residual stress of the edge cladding is an important parameter for bonding. The influence factors on the residual stress birefringence near the bonding interface are described in detail. The effects of fine annealing, polishing and bonding are investigated. The results indicate that the effects of the edge stress of samples on the residual stress near the bonded interface are in evidence; the poorer of polishing surface flatness makes, the larger birefringence near the cladding interface; and the low shrink percentage and modulus adhesive polymer have less impact for the residual stress near the interface.
