Induced steepening of femtosecond pulses

S. Dinev, A. Dreischuh

Abstract.

The femtosecond pulse conversion to the XUV has been studied theoretically for the first time in a gas-filled waveguide, including the influence of the pump-induced phase modulation on the phase matching conditions, waveguide propagation and signal pulse shape. The conversion of femtosecond pulses from excimer amplifiers to the range of 83 nm to 88 nm is discussed.
