    A novel pump-noise-suppressed semiconductor laser scheme is proposed. In this scheme, electrons injected into a stable intersubband state dressed by strongly resonant optical couplings stimulate amplitude-squeezed light with extremely low-threshold. Because of its high conversion efficiency and short stimulated emission lifetime at low injection current regime, this scheme can generate weak broad-band amplitude- squeezed light. We numerically estimate the characteristics of gain coefficient and output noise spectrum of this scheme.
