Single axial mode operation of a Q-switched Nd:YAG oscillator by injection seeding
Abstract
Stable Fourier transform-limited single axial mode operation of an unstable resonator Nd:YAG oscillator has been achieved by injection-seeding of an external signal. A detailed theoretical and experimental treatment of axial mode selection via injection seeding is presented. This study shows that the axial mode selection process in Q-switched lasers via injection seeding is quite different from the frequency locking in CW lasers via injection locking.
