Transient index of XeF
The phase shift due to the transient index of refraction for an e-beam excited XeF laser mix was measured. Large phase shifts have been predicted for this lasing species because of the asymmetric gain as a function of wavelength and transient absorption due to excited Ne. Previous measurement of the phase shift using a discharge-excited XeF probe indicated a transient phase shift of 5 rad for a peak gain length of about 1. These phase shifts vary with pumping leading to limits on the beam quality due to nonuniform pumping. The measurement was done using a 1 m long by 10 cm high e-beam of 350 kV and 10 A/cm/sup 2/ and 1 ..mu..s duration pumping a mixture of 3 atm Ne, 10 Torr Xe, and 2 Torr NF/sub 3/. The phase shifts were measured using a Mach-Zender interferometer and a narrow-band probe laser.
