KrF laser picosecond pulse source by stimulated scattering processes

摘要

A new short-pulse KrF laser source was developed by combining stimulated scattering processes, namely, Raman, Brillouin, and four-wave-mixing (FWM). Short pulses of 1.1 ps were obtained from 4 ns oscillator output. Only two commercial discharge KrF lasers are required for this system. This method is very simple and. could be extended to an ArF laser wavelength in principle. (C) 2002 Elsevier Science B.V. All rights reserved. [References: 14]
