This SBIR Phase I effort will establish the feasibility of fabricating advanced waveguide structures in potassium titanyl phosphate (KTP) capable of efficiently generating 25 to 40 mW of frequency converted light in the 395 to 480 nm. The key innovation in this effort is to utilize KTP waveguides in a single-pass frequency doubling device to efficiently produce the desired laser wavelengths and power. This approach is enabled by advances in waveguide processing which allows for the fabrication of uniform waveguide structures to be formed in commercially available KTP in conjunction with AdvR¿s patented submount poling technique. The results of this effort will lead to a compact, robust frequency doubling package suitable for operation in the 395 to 480 nm range with output powers of 25 to 40 mW which meets the objectives of the NIST SBIR topic 9.12.09-4.R Generation of Violet and Near-UV Radiation.
