Abstract
A double-chirped mirror structure with broadband negative dispersion was re alized with semiconductor technology. The necessary high precision of the f abrication was achieved by using special calibration structures. A single r eflection on the obtained low-loss mirror produces sufficient negative disp ersion for dispersion compensation in a femtosecond laser cavity. In this w ay we demonstrate 200 fs pulses from a compact Nd:glass laser without any a dditional dispersion compensation. (C) 1999 American Institute of Physics. [S0003-6951(99)00341-1].
