摘要
从棱镜对补偿色散的原理出发 ,介绍了Cr4 +∶YAG锁模激光器中色散补偿的特点 ,发现熔融石英作为色散补偿元件 ,不仅可以完全补偿二阶色散 ,而且三阶色散也得到了一定的补偿 ,并得到了脉冲宽度最小为 6 5fs ,中心波长为 15 2 0nm ,重复频率为 12
Based on the prisms dispersion compensation theory,the characters of the dispersion compensation in the self-starting mode-locked Cr 4+ ∶KG-2/3YAG laser was analysed,and it is found that not only the second-order dispersion was completely compensated,but also some of the third-order dispersion was compensated.The shortest pulse width was 65 fs
