Abstract

We report a pulsed, widely tunable Ti:sapphire laser pumped by an all-solid-state Q-switched intra-cavity frequency-doubled Nd:YAG laser with repetition rate of 7 KHz. Using two dense flint glass prisms as dispersion elements, the output wavelength could be continuously tuned over 675-970 nm, with spectral line-width of 2 nm. Gain-switching characteristics of Ti: sapphire laser shortened the pulse width to 17.6 ns. Well mode matching between pump and laser beam in the sapphire crystal and thermal design of the cavity ensured stable, efficient laser operation. The maximum output power was 6.2 W at 780 nm when the 532 nm pump power was 22 W; corresponding conversion efficiency was 28.2%.
