Quantum noise properties of a saturated amplifier


Journal Article

The quantum noise properties of a laser beam propagating through a laser-pumped potassium vapor in a near-Doppler-free configuration was investigated. Large excess noise that peaks at approximately 12 MHz with a width of approximately 15 Mhz was observed at the lowest input power due to nonlinear optical processes which degraded the coherence properties of the strong pump beam. The use of larger input beam powers led to an increase in the bandwidth of the excess quantum noise.
