摘要
Two Nd:YAG lasers at 1064 nm are independently frequency-stabilized to two separately located, vertically mounted ultrastable Fabry-Perot reference cavities. Measurements show that each laser system has achieved a most probable linewidth of 0.6 Hz and fractional frequency instability of similar to 1.2 x 10(-15) between 1 and 40 s averaging time. Systematic evaluation shows that the performance of each laser system is limited by thermal noise of the reference cavity. (C) 2013 Optical Society of America
