Low noise amplification and efficient squeezing from rate matched lasers

We investigate the quantum noise properties of lasers in which both the laser and pump form resonant cavity modes. We End that under conditions typical of solid-state lasers small signals placed on the pump beam of such systems can be found to be amplified on the laser output without incurring the usual 3 dB noise penalty associated with linear amplifiers. We also show that such systems can be very Efficient producers of squeezed light.
