Abstract

Summary form only given. We employ a diode-pumped microchip Nd:YVO/sub 4/ laser with multimode fiber feedback which forms a compound cavity. Different fiber lengths (1 m, 3 m, and 5 m) have been utilized. Meanwhile, with the attenuator, the feedback strength is adjustable. The lasing eigenmode frequency of the compound cavity is determined from the frequency arrangement of the Nd:YVO/sub 4/ laser cavity mode and the external cavity (fiber) modes for which the number of modes is very large. It is expected that the state of frustration can occur due to the small mode spacing of external cavity modes.
