Abstract

The creation of a high-coherence source of frequency- converted laser radiation as needed in multi-colored pulsed- holography requires the use of forward-SRS in the Dicke- narrowed line of hydrogen at low pressures (3 - 4 atm). However, the conversion efficiency of Raman amplifiers is traditionally not sufficient even at high pressure. In this article we report the experimental observation of Stokes pulses having approximately 1 Joule ((lambda) _s equals 674 nm, (lambda) _PUMP equals 526.5 nm) produced by forward Raman amplification with an energy conversion efficiency of up to 68%, a value close to the theoretical limit of 78%. The results of this study are now being used to produce a simple ultra-high efficiency 2-color Raman laser with parameters suitable for large and small format display holography.
