Abstract

A diode-pumped Q-cw (quasi-continuous wave) with simultaneous dual-wavelength laser operation at 744.8 nm and 860.9 nm in a single Ti: sapphire crystal is demonstrated. The birefringent filter is employed as the tuning apparatus for its low loss. A total output power of 4.8 W at the two wavelengths was achieved at the incident pump power of 23 W. To our knowledge, this is the highest value of the al-solid-state quasi-continuous dual-wavelength lasers which employ the Ti: sapphire as the gain medium..
