ABSTRACT:
In a frequency-shifted, low gain pulsed tunable laser, spatial and temporal build-up of regions of high intensity in the fundamental frequency is minimized by generating a frequency-narrowed fundamental wavelength, preferentially frequency shifting high energy portions of the fundamental wavelength, and separating the frequency-shifted portion. The remaining fundamental frequency can safely be coupled into a a fiber optic delivery means.
