2.3 dB of amplitude squeezing has been observed in a semiconductor laser with light injection from a singlemode semiconductor laser to one of the longitudinal modes of the slave laser. The slave laser operates as a semiconductor laser amplifier and oscillates at the injected mode, which differs from the free-running oscillation modes.
