Abstract

We demonstrate injection seeding of a pulsed, laser-pumped, titanium-doped-sapphire ring laser by both continuous-wave dye and diode lasers. As little as 100 μW of seed light is required to produce 4 mJ of 30-nsec TEM00 output having a bandwidth of less than 25 MHz FWHM. Using an atomic resonance filter we find that more than 99.9% of the energy is at the 780-nm seed wavelength. We discuss the spatial and longitudinal mode-matching requirements for successful seeding.
