Abstract
Enhancement of the transverse excess-noise factor is theoretically predicte d in optical laser cavities with tilted end mirrors and nonuniform transver se loss. In particular, it is shown that in a loss-guided laser close to th e plane-plane geometric instability boundary the excess-noise factor that i s induced by mirror tilting may largely exceed that predicted for the align ed cavity. This excess noise is related to beam walk-off induced by mirror tilting, which makes possible transient amplification of noise in the trans verse plane.
