Abstract
Polarization-resolved intensity noise has been investigated experimentally in a laser-diode-pumped isotropic microchip solid-state laser possessing spatially coherent polarization vector fields, which are formed by the coherent superposition of a pair of orthogonally polarized Ince–Gauss (IG) modes through the transverse mode locking. A large amount of noise reduction as compared with the total output, which is a coherent state, was observed for the stronger IG mode component by controlling the pump-beam focus.
