Efficient conversion of high-power narrow-band Ti:sapphire laser radiation to the mid-infrared in KTiOAsO(4).
Photon conversion efficiencies of 60% at 2.92 microm and 25% at 4.5 microm of a high-power injection-seeded Ti:sapphire laser have been achieved by difference frequency mixing with the new crystal KTiOAsO(4).
