We show that a light-stopping system with Raman amplification can overcome the gain-bandwidth constraint of slow light Raman amplification systems. The gain scales linearly with the time the pulse spends in the stopped state and is thus much larger than the gain experienced in a slow light system of the same length and operating bandwidth. We present a theoretical analysis of Raman amplification in such a light-stopping system and verify the results using numerical simulations.
