Abstract
A specific feature of multilayer quasiperiodic structures, namely, the inequality of the numbers of constituent layers of different type in a linear binary Fibonacci structure, allows to increase dispersion in comparison with periodic multilayers of the same length. Taking into account this, we have studied femtosecond light pulse compression in quasiperiodic nonsymmetric and symmetric Fibonacci-like structures. The theoretical analysis has shown that non-symmetric Fibonacci structures are more promising for the compressor design than periodic stacks. One of such advantages is decrease of laser pulse compression length in a quasiperiodic structure, which allows to reduce the spatial length of compression by 3-4 times (compared to periodic stacks) if the refraction index contrast is large enough (/spl Delta/n = 0.8).
