Abstract :
Sum frequency generation at 459 nm is demonstrated in a dual-wavelength coupled-cavity Ti:sapphire laser operating simultaneously at 808 nm and 1.06 μm. Enhanced operation of the Ti:sapphire laser at 1.06 μm is provided by a diode-pumped Nd:YAG active mirror. Comparable intracavity power is produced at both wavelengths, and 109 mW at 459 nm was generated with an intracavity KTP crystal. The 459-nm linewidth is 1 pm, and the conversion efficiency is 16%
