A Lyapunov functional in the chi2 dynamics of intracavity frequency-doubled lasers establishes a constant-intensity manifold that suppresses amplitude noise, experimentally confirmed by 100-fold contrast in an Nd:YVO4-LBO system.
The cavity length is taken to be 42 cm based on direct measurement of the IR longitu- dinal beat-note frequency at 358 MHz (corresponding to free spectral rangec/2L= 358 MHz)

Amplitude Noise Suppression in Frequency-Doubled Lasers: A Lyapunov Mechanism for Intensity Stabilization in Coupled Oscillator Systems
A Lyapunov functional in the chi2 dynamics of intracavity frequency-doubled lasers establishes a constant-intensity manifold that suppresses amplitude noise, experimentally confirmed by 100-fold contrast in an Nd:YVO4-LBO system.
