Paper Abstract

Femtosecond optical parametric oscillators (OPO), synchronously pumped by Ti:Sapphire lasers, operating in the near infrared (IR) region are an important light source now under active development. We report the results of our Ti:Sapphire synchronously pumped noncritically phase matched femtosecond OPOs that are based upon several crystals from the KTP family. The newly developed nonlinear crystal niobium doped KTP (Nb:KTP) has a greater birefringence than undoped KTP and is shown to extend the wavelength farther into the mid-IR. We report the first operation of a femtosecond OPO utilizing the solid-solution grown crystal Nb:KTP. Additionally, we show that CTA is very useful in mid-IR angle tuned OPOs.
