Modeling the induced-phase modulation and compression of UV laser pulses

S. G. Dinev, A. A. Dreischuh


The induced-phase modulation in a gas-filled hollow-core waveguide is modeled as a possible method for pulse compression in the UV using grating pair. The method has been applied to a number of excimer lasers and Raman-shifted wavelengths, predicting compression coefficients from 15 to 700. The limitations posed by system parameters, absorption, waveguide losses, and breakdown are discussed.
