Abstract

We present measurements of the power noise due to optical amplification in a Nd:YAG free-space traveling-wave amplifier as the amplifier transitions from the linear regime into the heavily saturated regime. The quantum noise behavior is demonstrated by saturating the gain of a 100-W class zigzag slab amplifier with a high-power beam and measuring the power noise detected by a single-spatial-mode probe beam traversing the same optical path through the amplifier.

摘要

我们展示了在Nd:YAG自由空间行波放大器中，当放大器从线性状态转变为深度饱和状态时，由光放大引起的功率噪声测量结果。通过用高功率光束使100瓦级锯齿形平板放大器的增益饱和，并测量通过放大器相同光路的单空间模式探测光束检测到的功率噪声，证明了量子噪声行为。
