Coherence enhanced transient lasing in XUV regime Academic Article uri icon


  • We report the effect of a coherent drive on transient lasing in three-level and configurations (cab). We show that the presence of a resonant coherent drive on the ac optical transition can yield an order of magnitude enhancement of the output laser energy on a ab extreme ultraviolet (XUV) or X-ray transition than with no coherent drive. We demonstrate the crucial role of coherence ac for the laser power enhancement. Contrary to the forward direction (with respect to the pump laser), where forward gain can be enhanced for some choice of the drive Rabi frequency c, coherent drive on the ac transition always suppresses the backward gain. 2012 by Astro, Ltd.
