High brightness, narrow-band, Ti:Al2O3 oscillator
Abstract
The injection-seeding of a short (about 30 cm) Ti:Al2O3 power oscillator with the output from a short-pulse, narrow-band, tunable, Ti:Al2O3 oscillator is reported. The frequency-doubled output from a Continuum YG681C Nd:YAG laser was used as the common pump source for both the seed laser and power oscillator. Good injection-seeding was observed with more than 20 ns delay; less delay than this resulted in poorer seeding. Minimizing the seed laser turn on time allowed harder pumping of the power oscillator, hence higher output energy, while maining good seeding. The spectral output from the power oscillator was analyzed using both an etalon and a 1-m MacPherson spectrometer. The seeded power oscillator is shown to closely replicate the seed laser output, operating on 2 or 3 longitudinal modes.
