摘要

A diode pumped stretched pulse additive pulse mode locked Er-doped fiber laser isused to seed a KCl:Tl+ color center amplifier crystal. The initial 1-nj chirped pulses are double passed through the amplifier, which is pumped by a 1-kHz Q switched Nd:YAG laser. The resulting 10 microJ pulses are then chirp compensated to 250-fs duration and are used to generate a spectral continuum. A few high-n2 materials are investigated for continuum generation, and spectral slicing of the continuum is demonstrated.
