We report the implementation of the KTP optical parametric oscillator pumped by a pulsed Ti:sapphire laser. Which include signal and idler, it may be continually tuned from 1.261 by way of 2.532 μm by varying the pump wavelength. Two important advancements have been obtained, such as the link in the sign and idler tuning ranges along with the high output pulse energy throughout the sign and idler tuning ...
