Abstract
Abstract A spherical mirror interferometer cavity for a mode-locked laser for increasing feedback path length and therefore the time between consecutive mode-locked pulses. In one embodiment a laser rod and a mode-locking dye cell are inserted within an interferometer cavity comprising two spherical mirrors. In another embodiment a spherical mirror optical delay line is inserted within the interferometer cavity of a mode-locked laser, and the laser pulses are injected into the delay line.
