Raman amplification of laser pulses in microcapillary and gas jet plasmas
Abstract
Experimental evidences of Raman amplification of ultrashort laser pulses in microcapillary and gas jet plasmas are presented. Investigations in very short microcapillaries (0.2 - 0.5 mm) with a broadband seed pulse show that the amplification factor is in agreement with the linear growth rate. Further experiments in a gas jet plasma confirm the Raman resonance by simultaneous plasma density measurements. This work is supported by NSF and DARPA grants.
