Abstract

Compression of femtosecond optical pulses using a single-mode fused silica fiber (glass fiber) always needs high amplification of laser output pulses because of a low nonlinear refractive index n_{2 G} of its fiber.¹⁾ This leads to some problems concerning the pulse stability in time and space, the pulse repetition rate, the optical damages to the glass fiber, and the precise adjustment of a big amplifier system. In order to solve these problems we inverstigated femtosecond-response, highly third-order nonlinear organic crystalline fibers.
