摘要
提出了一种六边形板条激光介质设计方法,由于激光在介质内部沿"之"字形光路传输,与COFFIN板条相比,同等抽运功率水平下六边形板条中热致波前畸变的幅值更低,并且更加容易补偿。此外,当激光沿板条长度方向入射时,激光在入射端面上的入射角即为布儒斯特角,且激光可以完全覆盖整个入射端面,在板条内部填充因子为1。
A method to design hexagonal slabs with zigzag optical path was presented.Compared with COFFIN slabs,the amplitude of thermal-induced wave-front distortion is lower and easier to be compensated in hexagonal slabs.Moreover,the laser beam enters the slab at Brewster angle when it is parallel to the slab length direction,and covers the entire slab and the entrance aperture,which means the fill factor is 1 inside the slab.
