!important">飞秒激光平均功率的提升大多集中在对MOPA系统中多级放大器或多通放大器的增益提取。考虑到兼顾脉冲能量的提升，多级光纤放大器一般作为前端预放大级，当非线性积累到一定程度就需要采用大截面积的激光增益介质。传统的固体放大器在数十瓦甚至二百瓦左右平均功率水平依然保持其兼顾激光功率和能量提升的优势，但其中的多级固体放大光路的每一级增益随着平均功率的升高而趋于饱和，尤其是对百瓦高功率信号的放大增益较小，导致高功率块状晶体放大器泵浦利用率低，制约了激光系统整体平均功率的进一步升高。<p

!important;overflow-wrap: break-word !important">此外，块状激光晶体在高泵浦强度下热效应严重，单纯依靠加大晶体外围热沉的热导率等方法依然不能有效消除热积累。增益介质自身结构的改良可有效改变其散热效果，如极大表面积的增益光纤就是以细长状几何形貌增大散热面积,这使其具有很好的散热功能,对产生的热量管理更为有效。同样的散热思路，薄板状结构增益介质的板条激光放大器，激光的放大在增益介质长度方向，而散热在增益介质厚度方向，由此可实现高功率、高能量连续或脉冲激光输出，且保持可控的光束质量。<p
