| Abstract: | We report on an injection-seeded Ti:sapphire laser pumped by the second harmonic of a Nd:YAG laser. Due to an excellent spatial
beam profile and narrow linewidth near the Fourier transform limit we are able to achieve high conversion efficiencies and
stable output power in harmonic generation as well as in sum and difference frequency mixing with the pump pulse. The laser
system can potentially cover a spectral range from 190 to over 6000 nm. |
