A GaAs/AlGaAs vertical-cavity surface-emitting laser was used to seed a titanium-sapphire laser oscillator. Both lasers were pumped synchronously by the same frequency-doubled Nd:YAG laser in the nanosecond range. Even at low injection level, we obtained a strong narrowing of the emission spectrum of the oscillator (from 30 to 1 mn), as well as its tunability over a broad range of wavelengths (from 775 to 805 run)
