| Abstract: | It has been investigated experimentally that the output energy and pulse-durational profile of first-order Stokes depend on the effective gain length due to the presence of the second-order SBS. The experimental results indicate that when the energy of an incident pump laser is strong enough and the effective gain length is relatively long, the self-accumulation of energy of first-order Stokes is enough to adequately reach a high peak power point to activate the second-order. The second-order SBS restrains the output energy of first-order to a great extent and plays an optical suppression role. |
