Diagram of performance measurement. An optical frequency divier (OFD) is used to connect the optical frequencies of a cavity-stabilized laser light at 1064 nm (f1064-1) and the light second-harmonic generated from a second independent 1064 nm laser light (f1064-2) as f532 = f1064-1/Rx. The value of Rx is obtained by measuring the beat frequency (fb) between f1064-1 and f1064-2 on an RF frequency counter with a self-referenced time base of f1064-1/k.
